Struct FallbackJudgment 

pub struct FallbackJudgment<P, F> { /* private fields */ }

A judgment backend that tries a primary backend first and falls back to a second backend when the primary fails in a way the fallback can fix.

Both backends answer through the shared JudgmentError taxonomy, so the decision of whether to fall back is one match over P’s error, not a per-backend special case.

Implementations

impl<P, F> FallbackJudgment<P, F>

pub const fn new(primary: P, fallback: F) -> Self

Composes primary with fallback.

pub const fn primary(&self) -> &P

The primary backend.

pub const fn fallback(&self) -> &F

The fallback backend.

Trait Implementations

impl<P, F> JudgmentProvider for FallbackJudgment<P, F>

where P: JudgmentProvider<Error = JudgmentError>, F: JudgmentProvider<Error = JudgmentError>,

type Error = JudgmentError

fn judge<'life0, 'async_trait>( &'life0 self, request: JudgmentRequest, ) -> Pin<Box<dyn Future<Output = Result<JudgmentResponse, JudgmentError>> + Send + 'async_trait>>

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

Answers every question in request over its state.
