Trait AuthProvider 

pub trait AuthProvider:
    Clone
    + Send
    + Sync
    + 'static {
    type Error: Into<CratestackError> + Send;

    // Required method
    fn authenticate(
        &self,
        request: &RequestContext<'_>,
    ) -> impl Future<Output = Result<CratestackContext, Self::Error>> + Send;
}

Resolves the caller of a request into a CratestackContext.

Implement authenticate as a plain async fn returning Result<CratestackContext, Self::Error> — the impl Future + Send return type below is only how the trait spells “the future must be Send”, and an async fn in the impl satisfies it directly. For the synchronous, header-only case a Clone + Send + Sync closure Fn(&http::HeaderMap) -> Result<CratestackContext, E> already implements this trait (see the blanket impl below).

Required Associated Types

type Error: Into<CratestackError> + Send

Required Methods

fn authenticate( &self, request: &RequestContext<'_>, ) -> impl Future<Output = Result<CratestackContext, Self::Error>> + Send

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl AuthProvider for CachedAuthProvider

type Error = CratestackError

impl<F, E> AuthProvider for F

where F: Clone + Send + Sync + 'static + for<'a> Fn(&'a HeaderMap) -> Result<CratestackContext, E>, E: Into<CratestackError> + Send,

type Error = E
