Enum ResolveDependencyOutcome 

#[non_exhaustive]
pub enum ResolveDependencyOutcome {
    Satisfied,
    Impossible,
    AlreadyResolved,
}

Typed outcome of crate::engine_backend::EngineBackend::resolve_dependency.

#[non_exhaustive] so additional variants (e.g. ChildSkipped cascade hints) can be added in minor releases without forcing match-arm churn on consumers.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Satisfied

Edge satisfied — downstream may become eligible.

Impossible

Edge made impossible — downstream becomes skipped.

AlreadyResolved

Already resolved (idempotent).

Trait Implementations

impl Clone for ResolveDependencyOutcome

fn clone(&self) -> ResolveDependencyOutcome

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResolveDependencyOutcome

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ResolveDependencyResult> for ResolveDependencyOutcome

fn from(r: ResolveDependencyResult) -> Self

Converts to this type from the input type.

impl PartialEq for ResolveDependencyOutcome

fn eq(&self, other: &ResolveDependencyOutcome) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
