pub struct IncomingFlashes { /* private fields */ }

Extractor for incoming flash messages.

See root module docs for an example.

Implementations

impl IncomingFlashes

pub fn iter(&self) -> Iter<'_>

Get an iterator over the flash messages.

pub fn len(&self) -> usize

Get the number of flash messages.

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for IncomingFlashes

fn clone(&self) -> IncomingFlashes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IncomingFlashes

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

Formats the value using the given formatter.

impl<S> FromRequestParts<S> for IncomingFlashes

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

type Rejection = (StatusCode, &'static str)

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<'a> IntoIterator for &'a IncomingFlashes

type Item = (Level, &'a str)

The type of the elements being iterated over.

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoResponse for IncomingFlashes

fn into_response(self) -> Response

Create a response.

impl IntoResponseParts for IncomingFlashes

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
