Implementations§
source§impl 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>

.
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
.
sourcepub fn remove<T: Send + Sync + 'static>(&mut self) -> Option<T>
pub fn remove<T: Send + Sync + 'static>(&mut self) -> Option<T>
Remove a type from this Extensions
.
If a extension of this type existed, it will be returned.
sourcepub fn into_http(self) -> Extensions
