Trait FutureFn 

pub trait FutureFn<T>:
    Fn() -> FutureBox<T>
    + Send
    + Sync { }

A trait for thread-safe, reference-counted closures that produce a boxed future.

This trait is used for storing and executing asynchronous operations that need to be sendable across threads, such as in the server’s request processing pipeline.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors
