Trait implemented by each middleware layer.

Required Methods

fn process<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 mut RequestContext, next: &'life2 dyn Next, ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Process the request. Call next.run(ctx) to continue the pipeline.

fn name(&self) -> &str

Human-readable name of this middleware.

Provided Methods

fn order(&self) -> i32

Execution order — lower values run first.
