Trait Implementations

impl<T: Clone> Clone for Body<T>

fn clone(&self) -> Body<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for Body<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default> Default for Body<T>

fn default() -> Body<T>

Returns the “default value” for a type.

impl<T> Deref for Body<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for Body<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T> From<T> for Body<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T> Handler for Body<T>

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

fn run<'life0, 'async_trait>( &'life0 self, conn: Conn, ) -> Pin<Box<dyn Future<Output = Conn> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Executes this handler, performing any modifications to the Conn that are desired.

fn before_send<'life0, 'async_trait>( &'life0 self, conn: Conn, ) -> Pin<Box<dyn Future<Output = Conn> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

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.

fn init<'life0, 'life1, 'async_trait>( &'life0 mut self, _info: &'life1 mut Info, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

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.

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

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,

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.

fn name(&self) -> Cow<'static, str>

Customize the name of your handler. This is used in Debug implementations. The default is the type name of this handler.

impl<T: Hash> Hash for Body<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: Ord> Ord for Body<T>

fn cmp(&self, other: &Body<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for Body<T>

fn eq(&self, other: &Body<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: PartialOrd> PartialOrd for Body<T>

fn partial_cmp(&self, other: &Body<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T> TryFromConn for Body<T>

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

type Error = Error

The Error type. Tf this is a Handler, you can extract Self directly in a ApiHandler signature, and Error will be called on Conn if try_from_conn fails.

fn try_from_conn<'life0, 'async_trait>( conn: &'life0 mut Conn, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Attempt to extract Self from &mut Conn, returning Error in case of failure
