Trait FromRequestParts

pub trait FromRequestParts<S>: Sized {
    type Rejection: IntoResponse;

    // Required method
    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 'life0: 'async_trait,
             'life1: 'async_trait,
             Self: 'async_trait;
}

Types that can be created from request parts.

Extractors that implement FromRequestParts cannot consume the request body and can thus be run in any order for handlers.

If your extractor needs to consume the request body then you should implement FromRequest and not FromRequestParts.

See axum::extract for more general docs about extractors.

Required Associated Types

type Rejection: IntoResponse

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

Required Methods

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

Perform the extraction.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
