Trait Middleware 

Source 
pub trait Middleware: Send + Sync {
    // Required method
    fn handle(
        &self,
        request: &Request,
        connection: &ConnectionInfo,
        next: &dyn Application,
    ) -> Result<Response, String>;
}
Expand description

A single middleware layer.

Receive the request, call next.execute(request, connection) to pass control to the next layer (or the inner application), and optionally inspect or transform the resulting response.

Short-circuit by returning a Response (or Err) without calling next.

Required Methods§

Source

fn handle( &self, request: &Request, connection: &ConnectionInfo, next: &dyn Application, ) -> Result<Response, String>

Dyn Compatibility§

This trait is dyn compatible.

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