Struct AnyExecutor 

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

A type-erased Executor that can hold any executor implementation.

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

Implementations

impl AnyExecutor

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

Create a new AnyExecutor wrapping the given executor.

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

Attempt to downcast to a concrete executor type by reference.

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

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

Attempt to downcast to a concrete executor type by value.

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