Struct aws_smithy_http_server::Extension[−][src]

pub struct Extension<T>(pub T);

Expand description

Extractor that gets a value from request extensions.

This is commonly used to share state across handlers.

If the extension is missing it will reject the request with a 500 Internal Server Error response.

Trait Implementations

[src]

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

[src]

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

Returns a copy of the value. Read more

1.0.0[src]

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

Performs copy-assignment from source. Read more

[src]

impl<T: Debug> Debug for Extension<T>

[src]

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

Formats the value using the given formatter. Read more

[src]

impl<T> Deref for Extension<T>

type Target = T

The resulting type after dereferencing.

[src]

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

Dereferences the value.

[src]

impl<T, B> FromRequest for Extension<T> where
T: Clone + Send + Sync + 'static,
B: Send,

type Rejection = ExtensionRejection

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

[src]

fn from_request<'life0, 'async_trait>(
 req: &'life0 mut RequestParts
) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>> where
 'life0: 'async_trait,
 Self: 'async_trait,

Perform the extraction.
