Struct Flash 

pub struct Flash { /* private fields */ }

Axum extractor for reading and writing flash messages within a request.

Requires FlashLayer to be applied to the router. Extraction fails with 500 Internal Server Error if the middleware is absent.

Implementations

impl Flash

pub fn set(&self, level: &str, message: &str)

Queue a flash message with an arbitrary severity level.

The message is stored in a signed cookie on the response and becomes available to the next request via Flash::messages.

pub fn success(&self, message: &str)

Queue a flash message with level "success".

pub fn error(&self, message: &str)

Queue a flash message with level "error".

pub fn warning(&self, message: &str)

Queue a flash message with level "warning".

pub fn info(&self, message: &str)

Queue a flash message with level "info".

pub fn messages(&self) -> Vec<FlashEntry>

Read incoming flash messages and mark them as consumed.

After calling this, the middleware clears the flash cookie on the response. Calling this multiple times within the same request returns the same data.

Trait Implementations

impl<S: Send + Sync> FromRequestParts<S> for Flash

type Rejection = Error

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

async fn from_request_parts( parts: &mut Parts, _state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.
