Struct tonic::Extensions
source · [−]pub struct Extensions { /* private fields */ }Expand description
A type map of protocol extensions.
Extensions can be used by Interceptor and Request to store extra data derived from
the underlying protocol.
Implementations
sourceimpl 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 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
pub fn into_http(self) -> Extensions
Convert to http::Extensions and consume self.
