Trait Middleware 

pub trait Middleware<C: Send + 'static>: Send + Sync {
    // Required method
    fn process<'life0, 'async_trait>(
        &'life0 self,
        ctx: C,
        next: Next<C>,
    ) -> Pin<Box<dyn Future<Output = Result<C>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

A middleware that transforms a context of type C.

Required Methods

fn process<'life0, 'async_trait>( &'life0 self, ctx: C, next: Next<C>, ) -> Pin<Box<dyn Future<Output = Result<C>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl<C, F, Fut> Middleware<C> for FnMiddleware<C, F>
