[−][src]Struct actix_web::dev::Extensions
A type map of request extensions.
Methods
impl Extensions
[src]
pub fn new() -> Extensions
[src]
Create an empty Extensions
.
pub fn insert<T>(&mut self, val: T) where
T: 'static,
[src]
T: 'static,
Insert a type into this Extensions
.
If a extension of this type already existed, it will be returned.
pub fn contains<T>(&self) -> bool where
T: 'static,
[src]
T: 'static,
Check if container contains entry
pub fn get<T>(&self) -> Option<&T> where
T: 'static,
[src]
T: 'static,
Get a reference to a type previously inserted on this Extensions
.
pub fn get_mut<T>(&mut self) -> Option<&mut T> where
T: 'static,
[src]
T: 'static,
Get a mutable reference to a type previously inserted on this Extensions
.
pub fn remove<T>(&mut self) -> Option<T> where
T: 'static,
[src]
T: 'static,
Remove a type from this Extensions
.
If a extension of this type existed, it will be returned.
pub fn clear(&mut self)
[src]
Clear the Extensions
of all inserted extensions.
