pub struct Identity;

Middleware which returns every message unchanged.

Trait Implementations

impl Clone for Identity

fn clone(&self) -> Identity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Identity

impl Debug for Identity

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

Formats the value using the given formatter.

impl Default for Identity

fn default() -> Identity

Returns the “default value” for a type.

impl Eq for Identity

impl<Message, State> MessageMiddleware<Message, State> for Identity

type Error = Infallible

An error which prevents the message from continuing through the chain.

async fn intercept( &mut self, _state: &mut State, message: Message, ) -> Result<Message, Self::Error>

Observes, mutates, or replaces one message and may await external policy, storage, or telemetry work before returning it.

impl PartialEq for Identity

fn eq(&self, other: &Identity) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for Identity

impl<Role, Phase, Message, State> TypedMiddleware<Role, Phase, Message, State> for Identity

type Error = Infallible

An error which prevents the message from continuing through the chain.

async fn intercept_typed( &mut self, _state: &mut State, message: Message, ) -> Result<Message, Self::Error>

Observes, mutates, or replaces one phase-legal message and may await while borrowing both the handler and caller-defined state.
