Methods
impl Extensions
[src]
pub fn new() -> Extensions
[src]

pub fn contains<T: 'static>(&self) -> bool
[src]
Check if container contains entry
pub fn get<T: 'static>(&self) -> Option<&T>
[src]
Get a reference to a type previously inserted on this Extensions
.
pub fn get_mut<T: 'static>(&mut self) -> Option<&mut T>
[src]
Get a mutable reference to a type previously inserted on this Extensions
.
pub fn remove<T: 'static>(&mut self) -> Option<T>
[src]
Remove a type from this Extensions
.
If a extension of this type existed, it will be returned.
pub fn clear(&mut self)
[src]
