Enum GuardedAliasSelection

Source

pub enum GuardedAliasSelection {

Expand description

What a reference’s guard and build evidence selects from the conditional alias arms on its alias chain.

Variants§

§

Proven

Evidence implies one arm at every conditional hop and the chain names exactly unit. candidates are the selected top-level declarations.

Fields

§unit: CodeUnit

§candidates: Vec<CodeUnit>

§

Alternatives(Vec<CodeUnit>)

Undecided or unresolvable arms remain. Each type is a candidate only.
