Fields§

§span: Span

Span of the original pattern that gave rise to this candidate.

§has_guard: bool

Whether this Candidate has a guard.

§match_pairs: SmallVec<[MatchPair<'pat, 'tcx>; 1]>

All of these must be satisfied…

§bindings: Vec<Binding<'tcx>>

…these bindings established…

§ascriptions: Vec<Ascription<'tcx>>

…and these types asserted…

§subcandidates: Vec<Candidate<'pat, 'tcx>>

…and if this is non-empty, one of these subcandidates also has to match…

§otherwise_block: Option<BasicBlock>

…and the guard must be evaluated; if it’s false then branch to otherwise_block.

§pre_binding_block: Option<BasicBlock>

The block before the bindings have been established.

§next_candidate_pre_binding_block: Option<BasicBlock>

The pre-binding block of the next candidate.
