Enum WriteAllNoCacheReason 

Source 
pub enum WriteAllNoCacheReason {
    FewerThanTwoOutputs,
    NoSharedRegisteredDerivedAlias,
    AmbiguousSharedDerivedAlias,
}
Expand description

Conservative reason no cache alias was selected for write_all.

Variants§

§

FewerThanTwoOutputs

Cache selection only helps when at least two outputs use a candidate.

§

NoSharedRegisteredDerivedAlias

No registered derived alias is shared by at least two selected outputs.

§

AmbiguousSharedDerivedAlias

Candidate relationships could not produce a deterministic cache frontier.
