# Fiber
|
||
|
||
[English](fiber.md) | 中文
|
||
|
||
fiber 是一个已加载的插件实例，包含其生命周期状态、经过校验的配置以及已注册的作用。`ctx.fiber` 是当前 fiber，`ctx.effect()` 会将调用委托给它。
|
||
|
||
### ctx.effect(execute, label?)
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Register a cleanup-aware effect on this fiber.
|
||
*
|
||
* `execute` runs immediately; the disposers it produces are collected and
|
||
* run (in reverse order) either when the returned disposer is called or
|
||
* when the fiber unloads, whichever comes first. Calling the disposer twice
|
||
* is a no-op. Throws `CordisError('INACTIVE_EFFECT')` if the fiber is
|
||
* already disposed, and `TypeError` if `execute` returns an invalid shape.
|
||
*
|
||
* @param execute — the effect body; see {@link Effect} for accepted shapes.
|
||
* @param label — effect label shown in `getEffects()` diagnostics.
|
||
* @returns a disposer that tears the effect down and settles once done.
|
||
*/
|
||
effect(execute: () => SyncEffect, label?: string): Disposable<Promise<void>>
|
||
effect(execute: () => Effect, label?: string): AsyncDisposable<Promise<void>>
|
||
```
|
||
|
||
在此 fiber 上注册一个支持清理的作用。
|
||
|
||
`execute` 会立即运行；它产生的清理函数将被收集，并在调用返回的清理函数或卸载 fiber 时按相反顺序运行，以先发生者为准。重复调用清理函数不会产生任何效果。如果 fiber 已经 dispose（资源释放），则抛出 `CordisError('INACTIVE_EFFECT')`；如果结构无效，则抛出 `TypeError`，表示 `execute` 返回了不受支持的结果。
|
||
|
||
- `execute`：作用主体；可接受的结构见 `Effect`。
|
||
- `label`：在 `getEffects()` 诊断信息中显示的作用标签。
|
||
|
||
**返回**一个用于撤销该作用的清理函数，并在清理完成后结算。
|
||
|
||

## Fiber 类
|
||
|
||
单次插件应用的运行时实例。

||
[源码](../../vendor/cordis/src/fiber.ts#L184)
|
||
|
||
### fiber.uid
|
||
|
||
```ts cordis-catalog

||
/** Unique id within the registry; 0 for the root fiber, `null` once disposed. */
|
||
public uid: number | null
|
||
```
|
||
|
||
在注册表中的唯一 id；根 fiber 的 id 为 0，dispose 后为 `null`。

|
||
/** Current lifecycle state; transitions emit `internal/status`. */
|
||
public state
|
||
```
|
||
|
||
当前生命周期状态；状态转换会发出 `internal/status`。
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L194)
|
||
|
||
### fiber.dispose
|
||
|
||
```ts cordis-catalog
|
||
/** Dispose this fiber: unload the plugin, then settle once cleanup finished. */
|
||
public readonly dispose: () => Promise<void>
|
||
```
|
||
|
||
dispose 此 fiber：卸载插件，并在清理完成后结算。

|
||
|
||
### fiber.store
|
||

```
|
||
|
||
加载期间所需服务实现的快照；其他情况下为 `undefined`。

|
||
|
||
### fiber.inertia
|
||
|

|
||
public inertia: Promise<void> | undefined
|
||
```
|
||
|
||
当前正在进行的加载或卸载转换；如果没有此类转换，则为 undefined。

|
||
|
||
### fiber.name
|
||
|
||
```ts cordis-catalog
|
||
/** The plugin's display name, inherited from the nearest named ancestor, else `'root'`. */
|
||
get name()
|
||
```
|
||
|
||
插件的显示名称，继承自最近的具名祖先；如果不存在，则为 `'root'`。
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L336)
|
||
|
||
### fiber.assertActive()
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Throw if the fiber has already been disposed.
|
||
*
|
||
* @returns nothing when the fiber is still active.
|
||
* @throws {CordisError} `INACTIVE_EFFECT` when the fiber's uid has been cleared.
|
||
*/
|
||
assertActive()
|
||
```
|
||
|
||
如果 fiber 已经 dispose，则抛出异常。
|
||
|
||
**返回**：fiber 仍处于活动状态时不返回任何内容。
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L351)
|
||
|
||
### fiber.effect(execute, label?)
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Register a cleanup-aware effect on this fiber.
|
||
*
|
||
* `execute` runs immediately; the disposers it produces are collected and
|
||
* run (in reverse order) either when the returned disposer is called or
|
||
* when the fiber unloads, whichever comes first. Calling the disposer twice
|
||
* is a no-op. Throws `CordisError('INACTIVE_EFFECT')` if the fiber is
|
||
* already disposed, and `TypeError` if `execute` returns an invalid shape.
|
||
*
|
||
* @param execute — the effect body; see {@link Effect} for accepted shapes.
|
||
* @param label — effect label shown in `getEffects()` diagnostics.
|
||
* @returns a disposer that tears the effect down and settles once done.
|
||
*/
|
||
effect(execute: () => SyncEffect, label?: string): Disposable<Promise<void>>
|
||
effect(execute: () => Effect, label?: string): AsyncDisposable<Promise<void>>
|
||
```
|
||
|
||
在此 fiber 上注册一个支持清理的作用。
|
||
|
||
`execute` 会立即运行；它产生的清理函数将被收集，并在调用返回的清理函数或卸载 fiber 时按相反顺序运行，以先发生者为准。重复调用清理函数不会产生任何效果。如果 fiber 已经 dispose，则抛出 `CordisError('INACTIVE_EFFECT')`；如果结构无效，则抛出 `TypeError`，表示 `execute` 返回了不受支持的结果。
|
||
|
||
- `execute`：作用主体；可接受的结构见 `Effect`。
|
||
- `label`：在 `getEffects()` 诊断信息中显示的作用标签。
|
||
|
||
**返回**一个用于撤销该作用的清理函数，并在清理完成后结算。
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L415)
|
||
|
||
### fiber.getEffects()
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Return metadata for currently registered effects.
|
||
*
|
||
* @returns one {@link EffectMeta} tree per labeled live effect.
|
||
*/
|
||
getEffects()
|
||
```
|
||
|
||
返回当前已注册作用的元数据。
|
||
|
||
**返回**：每个带标签的活动作用对应一棵 `EffectMeta` 树。
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L568)
|
||
|
||
### fiber.await()
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Wait for current lifecycle work and rethrow startup errors.
|
||
*
|
||
* @returns this fiber, once it has settled into a stable state.
|
||
* @throws the config-validation or plugin-startup error, if any.
|
||
*/
|
||
async await()
|
||
```
|
||
|
||
等待当前生命周期工作完成，并重新抛出启动错误。
|
||
|
||
**返回**：进入稳定状态后的此 fiber。
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L704)
|
||
|
||
### fiber.restart()
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Dispose and immediately reload this plugin with its current config.
|
||
*
|
||
* @returns a promise resolving once the reload settled.
|
||
* @throws {CordisError} `INACTIVE_EFFECT` when the fiber is already disposed.
|
||
*/
|
||
async restart()
|
||
```
|
||
|
||
dispose 此插件，并立即使用其当前配置重新加载。
|
||
|
||
**返回**一个在重新加载完成后兑现的 promise。
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L718)
|
||
|
||
### fiber.update(config, noSave?)
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Validate and apply new config, then restart the plugin.
|
||
*
|
||
* Runs the `internal/update` waterfall first, so update hooks (and HMR)
|
||
* can veto or replace the restart.
|
||
*
|
||
* @param config — the new raw config; validated before anything restarts.
|
||
* @param noSave — hint for persistence hooks not to write the change back.
|
||
* @returns the update waterfall result; the default restart returns a promise.
|
||
* @throws when validation, an update listener, or the restarted plugin fails.
|
||
*/
|
||
update(config: any, noSave = false)
|
||
```
|
||
|
||
校验并应用新配置，然后重新启动插件。
|
||
|
||
首先运行 `internal/update` waterfall（瀑布式事件），因此更新钩子（以及 HMR（热模块替换））可以否决或取代重新启动操作。
|
||
|
||
- `config`：新的原始配置；在任何内容重新启动前进行校验。
|
||
- `noSave`：提示持久化钩子不要写回此变更。
|
||
|
||
**返回**更新 waterfall 的结果；默认的重新启动操作返回一个 promise。
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L736)
|
||
|
||
## Effect
|
||
|
||
`ctx.effect()` 和插件启动所接受的作用主体结果。
|
||
|
||
可以是单个清理函数、兑现为清理函数的 promise，或生成多个清理函数的（可能为异步的）可迭代对象。生成器作用会在每个清理函数产生时将其注册。
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Effect body result accepted by `ctx.effect()` and plugin startup.
|
||
*
|
||
* Either a single disposer, a promise of one, or a (possibly async) iterable
|
||
* yielding several — generator effects register each yielded disposer as it
|
||
* is produced.
|
||
*/
|
||
type Effect<T = any> =
|
||
| SyncEffect<T>
|
||
| AsyncEffect<T>
|
||
```
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L83)
|
||
|
||
## Disposable
|
||
|
||
作用返回的函数，用于在资源释放期间释放资源。
|
||
|
||
拥有该函数的 fiber 卸载时，清理函数会按注册的相反顺序运行；清理函数可以是异步的，此时卸载过程会等待其完成。
|
||
|
||
```ts cordis-catalog
|
||
/**
|
||
* Function returned by an effect to release resources during disposal.
|
||
*
|
||
* Disposers run in reverse registration order when the owning fiber unloads;
|
||
* they may be async, in which case unloading awaits them.
|
||
*/
|
||
type Disposable<T = any> = () => T
|
||
```
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L74)
|
||
|
||
## EffectMeta
|
||
|
||
用于在诊断信息中公开嵌套作用标签的树节点。
|
||
|
||
```ts cordis-catalog
|
||
/** Tree node used to expose nested effect labels for diagnostics. */
|
||
interface EffectMeta {
|
||
/** Human-readable effect label, e.g. `ctx.on("event")` or `ctx.provide("name")`. */
|
||
label: string
|
||
/** Metadata of nested effects registered while this effect ran. */
|
||
children: EffectMeta[]
|
||
}
|
||
```
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L96)
|
||
|
||
## CordisError
|
||
|
||
具有稳定机器可读错误码的框架错误。
|
||
|
||
```ts cordis-catalog
|
||
/** Framework error with a stable machine-readable code. */
|
||
class CordisError extends Error {
|
||
/**
|
||
* @param code — the stable error code; also the default message.
|
||
* @param message — optional human-readable override.
|
||
*/
|
||
constructor(public code: CordisError.Code, message?: string)
|
||
}
|
||
|
||
/** Cordis error code definitions. */
|
||
namespace CordisError {
|
||
export type Code = keyof typeof Code
|
||
|
||
export const Code = {
|
||
INACTIVE_EFFECT: 'cannot create effect on inactive context',
|
||
} as const
|
||
}
|
||
```
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L157)
|
||
|
||
## ValidationError
|
||
|
||
插件配置未通过 standard-schema 校验时抛出的错误。
|
||
|
||
```ts cordis-catalog
|
||
/** Error raised when plugin configuration fails standard-schema validation. */
|
||
class ValidationError extends TypeError {
|
||
name = 'ValidationError'
|
||
|
||
/**
|
||
* Build the aggregated message from schema issues.
|
||
*
|
||
* @param issues — the standard-schema issues, one message line each.
|
||
*/
|
||
constructor(issues: readonly StandardSchemaV1.Issue[])
|
||
}
|
||
```
|
||
|
||
[源码](../../vendor/cordis/src/fiber.ts#L19)
