Struct RequestContextExt 

pub struct RequestContextExt(/* private fields */);

Wrapper type that can be injected into the dynamic extensions of a “Response”, in order to preserve the [Context]’s extensions of the Request which was used to produce the Response.

Methods from Deref<Target = Extensions>

pub fn maybe_set_parent_extensions( &mut self, frozen_extensions: Option<Arc<Extensions>>, ) -> &mut Extensions

Set parent extensions

pub fn set_parent_extensions( &mut self, frozen_extensions: Arc<Extensions>, ) -> &mut Extensions

Set parent extensions

pub fn unset_parent_extensions(&mut self) -> &mut Extensions

Set parent extensions

pub fn insert<T>(&mut self, val: T) -> Option<T>

where T: Clone + Send + Sync + 'static,

Insert a type into this Extensions.

If a extension of this type already existed, it will be returned.

pub fn insert_mut<T>(&mut self, val: T) -> &mut T

where T: Clone + Send + Sync + 'static,

Insert a type into this Extensions and get mutable reference

pub fn maybe_insert<T>(&mut self, val: Option<T>) -> Option<T>

where T: Clone + Send + Sync + 'static,

Insert a type only into this Extensions, if the value is Some(T).

See Self::insert for more information.

pub fn extend(&mut self, other: Extensions)

Extend these extensions with another Extensions.

pub fn clear(&mut self)

Clear the Extensions of all inserted extensions.

pub fn contains<T>(&self) -> bool

where T: Send + Sync + 'static,

Returns true if the Extensions or parents contains the given type.

pub fn get<T>(&self) -> Option<&T>

where T: Send + Sync + 'static,

Get a shared reference to a type previously inserted on this Extensions or any of the parents

pub fn get_mut<T>(&mut self) -> Option<&mut T>

where T: Send + Sync + 'static,

Get an exclusive reference to a type previously inserted on this Extensions.
