Expand description

Provides an extension trait for both trillium::Headers and also trillium::Conn for setting and getting various parsed caching headers.

Required Methods§

source

fn etag(&self) -> Option<EntityTag>

returns an EntityTag if these headers contain an Etag header.

source

fn set_etag(&mut self, entity_tag: &EntityTag)

sets an etag header from an EntityTag.

source

fn last_modified(&self) -> Option<SystemTime>

returns a parsed timestamp if these headers contain a Last-Modified header.

source

fn set_last_modified(&mut self, system_time: SystemTime)

sets a formatted Last-Modified header from a timestamp.

source

fn cache_control(&self) -> Option<CacheControlHeader>

returns a parsed CacheControlHeader if these headers include a Cache-Control header. Note that if this is called on a [Conn], it returns the request [Cache-Control] header.

source

fn set_cache_control(&mut self, cache_control: impl Into<CacheControlHeader>)

sets a Cache-Control header on these headers. Note that this is valid in both request and response contexts, and specific directives have different meanings.

source

fn if_modified_since(&self) -> Option<SystemTime>

returns a parsed If-Modified-Since header if one exists

source

fn if_none_match(&self) -> Option<EntityTag>

returns a parsed EntityTag header if there is an If-None-Match header.

source

fn set_vary<I, N>(&mut self, vary: I)
where I: IntoIterator<Item = N>, N: Into<HeaderName<'static>>,

sets the Vary header to a collection of Into

Provided Methods§

source

fn with_cache_control( self, cache_control: impl Into<CacheControlHeader>, ) -> Self

chainable method to set cache control and return self. primarily useful on Conn

source

fn with_last_modified(self, system_time: SystemTime) -> Self

chainable method to set last modified and return self. primarily useful on Conn

source

fn with_etag(self, entity_tag: &EntityTag) -> Self

chainable method to set etag and return self. primarily useful on Conn

source

fn with_vary<I, N>(self, vary: I) -> Self
where I: IntoIterator<Item = N>, N: Into<HeaderName<'static>>,

chainable method to set vary and return self. primarily useful on Conn

This trait is not object safe.
