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.

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
