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

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

A constructor for array and slice patterns.

Fields

array_len: Option<usize>

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<usize>, kind: SliceKind) -> Self

fn arity(self) -> usize

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

See Constructor::is_covered_by

Trait Implementations

impl Clone for Slice

fn clone(&self) -> Slice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Slice

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

Formats the value using the given formatter.

impl PartialEq<Slice> for Slice

fn eq(&self, other: &Slice) -> 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.

impl Eq for Slice

impl StructuralEq for Slice

impl StructuralPartialEq for Slice

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.
