Trait FnContextStatic 

pub trait FnContextStatic<Fut, T>: FnContext<Fut> + 'static
where
    Fut: Future<Output = T> + Send,
{ }

A trait for static, sendable, synchronous functions that return a future.

This trait ensures that a hook function is safe to be sent across threads and has a static lifetime, making it suitable for use in long-lived components of the application, such as the main router.

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl<F, Fut, T> FnContextStatic<Fut, T> for F

where F: FnContext<Fut> + 'static, Fut: Future<Output = T> + Send,

A blanket implementation for static, sendable, synchronous functions that return a future.

This trait is used for handlers that are known at compile time, ensuring they are safe to be sent across threads and have a static lifetime. This is crucial for handlers that are part of the application’s long-lived state.
