Struct BoxRunnableWith 

pub struct BoxRunnableWith<T, E> { /* private fields */ }

Box-based runnable with mutable input.

BoxRunnableWith<T, E> stores a Box<dyn FnMut(&mut T) -> Result<(), E>> and can be called repeatedly.

Implementations

impl<T, E> BoxRunnableWith<T, E>

pub fn new<F>(function: F) -> Self

where F: FnMut(&mut T) -> Result<(), E> + 'static,

Creates a new runnable-with.

Wraps the provided closure in the appropriate smart pointer type for this runnable-with implementation.

pub fn new_with_name<F>(name: &str, function: F) -> Self

where F: FnMut(&mut T) -> Result<(), E> + 'static,

Creates a new named runnable-with.

Wraps the provided closure and assigns it a name, which is useful for debugging and logging purposes.

pub fn new_with_optional_name<F>(function: F, name: Option<String>) -> Self

where F: FnMut(&mut T) -> Result<(), E> + 'static,

Creates a new named runnable-with with an optional name.

Wraps the provided closure and assigns it an optional name.

pub fn name(&self) -> Option<&str>

Gets the name of this runnable-with.

Returns

Returns Some(&str) if a name was set, None otherwise.

pub fn set_name(&mut self, name: &str)

Sets the name of this runnable-with.

Parameters

• name - The name to set for this runnable-with

pub fn clear_name(&mut self)

Clears the name of this runnable-with.

pub fn and_then<N>(self, next: N) -> BoxRunnableWith<T, E>

where N: RunnableWith<T, E> + 'static, T: 'static, E: 'static,

Chains another runnable after this runnable succeeds.

Parameters

• next - The runnable to execute after this runnable succeeds.

Returns

A runnable executing both actions in sequence.

pub fn then_callable_with<R, C>(self, callable: C) -> BoxCallableWith<T, R, E>

where C: CallableWith<T, R, E> + 'static, T: 'static, R: 'static, E: 'static,

Runs this runnable before a callable.

The callable is not executed if this runnable returns Err.

Parameters

• callable - The callable to execute after this runnable succeeds.

Returns

A callable producing the second computation’s result.
