}

A fallible, reusable action that receives mutable input.

Conceptually this is FnMut(&mut T) -> Result<(), E> with task-oriented naming. It is useful for executor-style APIs that run an action with access to protected state, such as a value held under a lock.

Type Parameters

• T - The mutable input type.
• E - The error value returned when the action fails.

Required Methods

fn run_with(&mut self, input: &mut T) -> Result<(), E>

Executes the action with mutable input.

Parameters

• input - The mutable input passed to this task.

Returns

Returns Ok(()) when the action succeeds, or Err(E) when it fails. The exact error meaning is defined by the concrete runnable.

Provided Methods

fn into_box(self) -> BoxRunnableWith<T, E>

where Self: Sized + 'static,

Converts this runnable into a boxed runnable.

Returns

A BoxRunnableWith<T, E>.

fn into_rc(self) -> RcRunnableWith<T, E>

where Self: Sized + 'static,

Converts this runnable into an Rc runnable.

Returns

A RcRunnableWith<T, E>.

fn into_arc(self) -> ArcRunnableWith<T, E>

where Self: Sized + Send + 'static,

Converts this runnable into an Arc runnable.

Returns

An ArcRunnableWith<T, E>.

fn into_fn(self) -> impl FnMut(&mut T) -> Result<(), E>

where Self: Sized + 'static,

Converts this runnable into a mutable closure.

Returns

A closure implementing FnMut(&mut T) -> Result<(), E>.

fn to_box(&self) -> BoxRunnableWith<T, E>

where Self: Clone + Sized + 'static,

Converts this runnable into a boxed runnable without consuming self.

Returns

A BoxRunnableWith<T, E> built from a clone of this runnable.

fn to_rc(&self) -> RcRunnableWith<T, E>

where Self: Clone + Sized + 'static,

Converts this runnable into an Rc runnable without consuming self.

Returns

A RcRunnableWith<T, E> built from a clone of this runnable.

fn to_arc(&self) -> ArcRunnableWith<T, E>

where Self: Clone + Send + Sized + 'static,

Converts this runnable into an Arc runnable without consuming self.

Returns

An ArcRunnableWith<T, E> built from a clone of this runnable.

fn to_fn(&self) -> impl FnMut(&mut T) -> Result<(), E>

where Self: Clone + Sized + 'static,

Converts this runnable into a mutable closure without consuming self.

Returns

A closure implementing FnMut(&mut T) -> Result<(), E>.

fn into_callable_with(self) -> BoxCallableWith<T, (), E>

where Self: Sized + 'static,

Converts this runnable into a callable returning unit.

Returns

A BoxCallableWith<T, (), E> that runs this task and returns unit on success.
