Expand description
Provides an extension trait for both trillium::Headers
and
also trillium::Conn
for setting and getting various parsed
caching headers.
Required Methods§
sourcefn etag(&self) -> Option<EntityTag>
fn etag(&self) -> Option<EntityTag>
returns an EntityTag
if these headers contain an Etag
header.
sourcefn last_modified(&self) -> Option<SystemTime>
fn last_modified(&self) -> Option<SystemTime>
returns a parsed timestamp if these headers contain a Last-Modified
header.
sourcefn set_last_modified(&mut self, system_time: SystemTime)
fn set_last_modified(&mut self, system_time: SystemTime)
sets a formatted Last-Modified
header from a timestamp.
sourcefn cache_control(&self) -> Option<CacheControlHeader>
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.
sourcefn set_cache_control(&mut self, cache_control: impl Into<CacheControlHeader>)
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.
sourcefn if_modified_since(&self) -> Option<SystemTime>
fn if_modified_since(&self) -> Option<SystemTime>
returns a parsed If-Modified-Since
header if one exists
sourcefn if_none_match(&self) -> Option<EntityTag>
fn if_none_match(&self) -> Option<EntityTag>
returns a parsed EntityTag
header if there is an If-None-Match
header.
Provided Methods§
sourcefn with_cache_control(
self,
cache_control: impl Into<CacheControlHeader>,
) -> Self
fn with_cache_control( self, cache_control: impl Into<CacheControlHeader>, ) -> Self
chainable method to set cache control and return self. primarily useful on Conn
sourcefn with_last_modified(self, system_time: SystemTime) -> Self
fn with_last_modified(self, system_time: SystemTime) -> Self
chainable method to set last modified and return self. primarily useful on Conn
sourcefn with_etag(self, entity_tag: &EntityTag) -> Self
fn with_etag(self, entity_tag: &EntityTag) -> Self
chainable method to set etag and return self. primarily useful on Conn
