Struct Extension

pub struct Extension<T>(pub T);

A Specialized extractor for the Extensions of the current JobCall.

Any type that is stored in the Extensions of the current JobCall can be extracted using this extractor.

For Optional extraction, you can use this extractor with Option<Extension<T>> where T is the type you want to extract.

Trait Implementations

impl<T: Clone> Clone for Extension<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Deref for Extension<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T> DerefMut for Extension<T>

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

Mutably dereferences the value.

impl<Ctx, T> FromJobCallParts<Ctx> for Extension<T>

where T: Send + Sync + Clone + 'static, Ctx: Send + Sync + 'static,

type Rejection = ExtensionNotFound

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a job result.

async fn from_job_call_parts( parts: &mut JobCallParts, _: &Ctx, ) -> Result<Self, Self::Rejection>

Perform the extraction.

impl<Ctx, T> OptionalFromJobCallParts<Ctx> for Extension<T>

where T: Send + Sync + Clone + 'static, Ctx: Send + Sync + 'static,

type Rejection = Infallible

If the extractor fails, it will use this “rejection” type.

async fn from_job_call_parts( parts: &mut JobCallParts, _: &Ctx, ) -> Result<Option<Self>, Self::Rejection>

Perform the extraction.
