Struct MirrorLayer 

pub struct MirrorLayer { /* private fields */ }

Available on non-WebAssembly only.

A Mirror as middleware: copies the request, then hands it on.

Implementations

impl MirrorLayer

pub fn new(mirror: Mirror) -> MirrorLayer

Trait Implementations

impl Clone for MirrorLayer

fn clone(&self) -> MirrorLayer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MirrorLayer

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Middleware for MirrorLayer

fn runs_inline(&self, _request: &Request, _connection: &ConnectionInfo) -> bool

Queueing a copy never blocks.

fn accepts_streamed_body( &self, _request: &Request, _connection: &ConnectionInfo, ) -> bool

A streamed body passes through untouched (and isn’t mirrored).

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

fn is_passthrough( &self, _request: &Request, _connection: &ConnectionInfo, ) -> bool

true when handle would do nothing for request but call next (e.g. a rate limit that isn’t configured). A WithMiddleware stack offers the inner application’s execute_async only if every layer passes the request through. Default false.

fn answers_streamed_body( &self, _request: &Request, _connection: &ConnectionInfo, ) -> bool

true when this layer answers request itself — it doesn’t call next — and reads its body as a stream (a proxy forwarding it as it arrives). The body is then streamed whatever the layers after it and the application would say. Requires accepts_streamed_body. Since 18.3.0.

fn layer_name(&self) -> &'static str

A short name for this layer, as tools that describe an app list it (Application::middleware_names): by default the type’s name without its module path or generic parameters (CacheLayer). Since 18.28.0.
