Struct http_types::Extensions[−][src]

pub struct Extensions { /* fields omitted */ }

A type to store extra data inside Request and Response.

Store and retrieve values by TypeId. This allows storing arbitrary data that implements Sync + Send + 'static. This is useful when for example implementing middleware that needs to send values.

Implementations

impl Extensions[src]

pub fn insert<T: Send + Sync + 'static>(&mut self, val: T) -> Option<T>[src]

Insert a value into this Extensions.

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 Extensions.

pub fn get_mut<T: 'static>(&mut self) -> Option<&mut T>[src]

Get a mutable reference to a value previously inserted on this Extensions.

pub fn remove<T: 'static>(&mut self) -> Option<T>[src]

Remove a value from this Extensions.

If a value of this type exists, it will be returned.

pub fn clear(&mut self)[src]

Clear the Extensions of all inserted values.
