Struct rustc_mir_build::thir::pattern::deconstruct_pat::Slice

pub(super) struct Slice {
    array_len: Option<u64>,
    kind: SliceKind,
}

A constructor for array and slice patterns.

Fields

array_len: Option<u64>

None if the matched value is a slice, Some(n) if it is an array of size n.

kind: SliceKind

The kind of pattern it is: fixed-length [x, y] or variable length [x, .., y].

Implementations

impl Slice

fn new(array_len: Option<u64>, kind: SliceKind) -> Self

fn arity(self) -> u64

fn is_covered_by(self, other: Self) -> bool
