Struct rustc_mir_build::build::matches::FlatPat

struct FlatPat<'pat, 'tcx> {
    match_pairs: Vec<MatchPairTree<'pat, 'tcx>>,
    extra_data: PatternExtraData<'tcx>,
}

A pattern in a form suitable for lowering the match tree, with all irrefutable patterns simplified away, and or-patterns sorted to the end.

Here, “flat” indicates that the pattern’s match pairs have been recursively simplified by Builder::simplify_match_pairs. They are not necessarily flat in an absolute sense.

Will typically be incorporated into a Candidate.

Fields

match_pairs: Vec<MatchPairTree<'pat, 'tcx>>

To match the pattern, all of these must be satisfied…

extra_data: PatternExtraData<'tcx>

Implementations

impl<'tcx, 'pat> FlatPat<'pat, 'tcx>

fn new( place: PlaceBuilder<'tcx>, pattern: &'pat Pat<'tcx>, cx: &mut Builder<'_, 'tcx>, ) -> Self

Creates a FlatPat containing a simplified MatchPairTree list/forest for the given pattern.

Trait Implementations

impl<'pat, 'tcx> Clone for FlatPat<'pat, 'tcx>

fn clone(&self) -> FlatPat<'pat, 'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'pat, 'tcx> Debug for FlatPat<'pat, 'tcx>

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
