Struct ModelFallbackPolicy 

pub struct ModelFallbackPolicy { /* private fields */ }

Explicit authority for selecting another physical model after a failure.

Safe errors are always eligible. Errors with unknown retry safety are eligible only when their kind is explicitly added. Cancellation and errors marked unsafe are never eligible.

Implementations

impl ModelFallbackPolicy

pub const fn safe_only() -> Self

Creates the conservative policy: only errors explicitly marked safe.

pub fn allow_unknown(self, kind: ModelErrorKind) -> Self

Allows fallback for one error kind whose retry safety is unknown.

This is explicit authority to risk duplicate provider cost. It never overrides cancellation or an error marked unsafe.
