Trait AuthenticationStrategy 

pub trait AuthenticationStrategy<I>: Send + Sync {
    // Required method
    fn authenticate<'life0, 'life1, 'async_trait>(
        &'life0 self,
        parts: &'life1 Parts,
    ) -> Pin<Box<dyn Future<Output = Result<Option<I>, AuthError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Trait for an authentication strategy.

A strategy is responsible for extracting credentials from a request and validating them to produce an identity.

Required Methods

fn authenticate<'life0, 'life1, 'async_trait>( &'life0 self, parts: &'life1 Parts, ) -> Pin<Box<dyn Future<Output = Result<Option<I>, AuthError>> + Send + 'async_trait>>

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

Attempt to authenticate the request.

Returns:

• Ok(Some(identity)) if authentication was successful.
• Ok(None) if the strategy did not find relevant credentials (e.g., missing header).
• Err(AuthError) if authentication failed (e.g., invalid token, DB error).
