Struct AnyLocalExecutor 

pub struct AnyLocalExecutor(/* private fields */);

A type-erased LocalExecutor that can hold any local executor implementation.

This allows for runtime selection of executors and storing different executor types in the same collection.

Implementations

impl AnyLocalExecutor

pub fn new(executor: impl LocalExecutor + 'static) -> Self

Create a new AnyLocalExecutor wrapping the given local executor.

pub fn downcast_ref<E: LocalExecutor + 'static>(&self) -> Option<&E>

Attempt to downcast to a concrete local executor type by reference.

Returns Some(&E) if the underlying executor is of type E, None otherwise.

pub fn downcast<E: LocalExecutor + 'static>(self) -> Result<Box<E>, Self>

Attempt to downcast to a concrete local executor type by value.

Returns Ok(Box<E>) if the underlying executor is of type E, Err(Self) otherwise (returning the original AnyLocalExecutor).
