#[non_exhaustive]pub enum CacheControlDirective {
}
Expand description
An enum representation of the
Cache-Control
directives.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Performs one-time async set up on a mutable borrow of the
Handler before the server starts accepting requests. This
allows a Handler to be defined in synchronous code but perform
async setup such as establishing a database connection or
fetching some state from an external source. This is optional,
and chances are high that you do not need this. Read more

Performs any final modifications to this conn after all handlers
have been run. Although this is a slight deviation from the simple
conn->conn->conn chain represented by most Handlers, it provides
an easy way for libraries to effectively inject a second handler
into a response chain. This is useful for loggers that need to
record information both before and after other handlers have run,
as well as database transaction handlers and similar library code. Read more
source§fn has_upgrade(&self, _upgrade: &Upgrade<BoxedTransport>) -> bool
fn has_upgrade(&self, _upgrade: &Upgrade<BoxedTransport>) -> bool
predicate function answering the question of whether this Handler
would like to take ownership of the negotiated Upgrade. If this
returns true, you must implement
Handler::upgrade
. The first
handler that responds true to this will receive ownership of the
trillium::Upgrade
in a subsequent call to Handler::upgrade
source§fn upgrade<'life0, 'async_trait>(
&'life0 self,
_upgrade: Upgrade<BoxedTransport>,
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
'life0: 'async_trait,
Self: 'async_trait,
fn upgrade<'life0, 'async_trait>(

_upgrade: Upgrade<BoxedTransport>,
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
'life0: 'async_trait,
Self: 'async_trait,
This will only be called if the handler reponds true to
Handler::has_upgrade
and will only be called once for this
upgrade. There is no return value, and this function takes
exclusive ownership of the underlying transport once this is
called. You can downcast the transport to whatever the source
transport type is and perform any non-http protocol communication
that has been negotiated. You probably don’t want this unless
you’re implementing something like websockets. Please note that
for many transports such as TcpStreams, dropping the transport
(and therefore the Upgrade) will hang up / disconnect.source§impl PartialEq for CacheControlDirective
