Struct Extensions 

pub struct Extensions { /* private fields */ }

A type-keyed map for attaching arbitrary data to a connection or request.

Modelled on http::Extensions, implemented here to avoid the dependency. Used to carry attestation on a connection and verified mission-token claims on a request, without either concept leaking into this crate’s core types.

Stored values must be Clone so that the containing RequestContext stays Clone.

Implementations

impl Extensions

pub fn new() -> Self

pub fn insert<T: Clone + Send + Sync + 'static>( &mut self, value: T, ) -> Option<T>

Insert a value, returning the previous one of the same type, if any.

pub fn get<T: Clone + Send + Sync + 'static>(&self) -> Option<&T>

pub fn get_mut<T: Clone + Send + Sync + 'static>(&mut self) -> Option<&mut T>

pub fn remove<T: Clone + Send + Sync + 'static>(&mut self) -> Option<T>

pub fn contains<T: Clone + Send + Sync + 'static>(&self) -> bool

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize
