Middleware trait for request/response processing

Required Methods§

Source

fn before_request<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, request: &'life1 mut HttpRequest, context: &'life2 mut RequestContext, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Process request before handler

Source

fn after_response<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, request: &'life1 HttpRequest, response: &'life2 mut HttpResponse, context: &'life3 RequestContext, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Process response after handler

Source

fn on_error<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, error: &'life1 FerrumError, context: &'life2 RequestContext, ) -> Pin<Box<dyn Future<Output = Option<HttpResponse>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Handle middleware errors

Source

fn name(&self) -> &str

Get middleware name

Source

fn priority(&self) -> i32

Get middleware priority (lower numbers run first)

Dyn Compatibility§

This trait is dyn compatible.

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