Enum rustc_mir_build::thir::pattern::deconstruct_pat::SliceKind

enum SliceKind {
    FixedLen(usize),
    VarLen(usize, usize),
}

Variants

FixedLen(usize)

Patterns of length n ([x, y]).

VarLen(usize, usize)

Patterns using the .. notation ([x, .., y]). Captures any array constructor of length >= i + j. In the case where array_len is Some(_), this indicates that we only care about the first i and the last j values of the array, and everything in between is a wildcard _.

Implementations

impl SliceKind

fn arity(self) -> usize

fn covers_length(self, other_len: usize) -> bool

Whether this pattern includes patterns of length other_len.

Trait Implementations

impl Clone for SliceKind

fn clone(&self) -> SliceKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SliceKind

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

Formats the value using the given formatter.

impl PartialEq<SliceKind> for SliceKind

fn eq(&self, other: &SliceKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
