Trait Implementations

impl Clone for Flash

fn clone(&self) -> Flash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Flash

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

Formats the value using the given formatter.

impl<S> FromRequestParts<S> for Flash

where S: Send + Sync, Config: FromRef<S>,

type Rejection = Infallible

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

fn from_request_parts<'life0, 'life1, 'async_trait>( _parts: &'life0 mut Parts, state: &'life1 S, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>>

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

Perform the extraction.

impl IntoResponseParts for Flash

type Error = Infallible

The type returned in the event of an error.

fn into_response_parts( self, res: ResponseParts, ) -> Result<ResponseParts, Self::Error>

Set parts of the response
