source · [−]pub struct Extensions { /* private fields */ }
Expand description
A type map of protocol extensions.
Extensions
can be used by Interceptor
and Request
to store extra data derived from
the underlying protocol.
Implementations
sourceimpl Extensions
impl Extensions
sourcepub fn insert<T: Send + Sync + 'static>(&mut self, val: T) -> Option<T>
pub fn insert<T: Send + Sync + 'static>(&mut self, val: T) -> Option<T>
Insert a type into this Extensions
.
If a extension of this type already existed, it will be returned.
sourcepub fn get<T: Send + Sync + 'static>(&self) -> Option<&T>
pub fn get<T: Send + Sync + 'static>(&self) -> Option<&T>
Get a reference to a type previously inserted on this Extensions
.
sourcepub fn get_mut<T: Send + Sync + 'static>(&mut self) -> Option<&mut T>
pub fn get_mut<T: Send + Sync + 'static>(&mut self) -> Option<&mut T>
Get a mutable reference to a type previously inserted on this Extensions
.
