Struct apollo_router::Extensions
source ยท pub struct Extensions { /* private fields */ }
Expand description
A type map of protocol extensions.
Extensions
can be used by Request
and Response
to store
extra data derived from the underlying protocol.
Implementationsยง
sourceยงimpl 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
.
sourcepub fn contains_key<T: Send + Sync + 'static>(&self) -> bool
pub fn contains_key<T: Send + Sync + 'static>(&self) -> bool
Returns true
type has been stored in Extensions
.
