Struct type_map::TypeMap [−][src]
The typemap container
Implementations
impl TypeMap
[src]
pub fn new() -> Self
[src]
Create an empty TypeMap
.
pub fn insert_kv_pair(&mut self, KvPair: KvPair) -> Option<KvPair>
[src]
Insert a prepared KvPair
into this TypeMap
.
If a value of this type already exists, it will be returned.
pub fn insert<T: 'static>(&mut self, val: T) -> Option<T>
[src]
Insert a value into this TypeMap
.
If a value of this type already exists, it will be returned.
pub fn contains<T: 'static>(&self) -> bool
[src]
Check if container contains value for type
pub fn get<T: 'static>(&self) -> Option<&T>
[src]
Get a reference to a value previously inserted on this TypeMap
.
pub fn get_mut<T: 'static>(&mut self) -> Option<&mut T>
[src]
Get a mutable reference to a value previously inserted on this TypeMap
.
pub fn remove<T: 'static>(&mut self) -> Option<T>
[src]
Remove a value from this TypeMap
.
If a value of this type exists, it will be returned.
pub fn clear(&mut self)
[src]
Clear the TypeMap
of all inserted values.
pub fn entry<T: 'static>(&mut self) -> Entry<'_, T>
[src]
Get an entry in the TypeMap
for in-place manipulation.
