Struct FlashExtractor 

pub struct FlashExtractor(pub Vec<FlashMessage>);

Extractor for flash messages

Extracts flash messages from the session and clears them from the session data. Messages are typically shown once and then cleared (flash = one-time display).

Note

This extractor takes the flash messages from the session data in extensions, clearing them so they won’t be persisted back. The middleware will save the modified session data (without the flashes) on response.

Example

use acton_htmx::extractors::FlashExtractor;

async fn handler(FlashExtractor(messages): FlashExtractor) {
    for msg in messages {
        println!("Flash: {:?} - {}", msg.level, msg.message);
    }
}

impl<S> FromRequestParts<S> for FlashExtractor

where S: Send + Sync,

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.

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

Perform the extraction.
