Struct ArrayPattern 

pub struct ArrayPattern<'ast> {
    pub patterns: &'ast [Pattern<'ast>],
    pub tail: TailPattern,
    pub pos: TermPos,
}

An array pattern.

Fields

patterns: &'ast [Pattern<'ast>]

The patterns of the elements of the array.

tail: TailPattern

The tail of the pattern, indicating if the pattern is open, i.e. if it ended with an ellipsis, capturing the rest or not.

pos: TermPos

Implementations

impl ArrayPattern<'_>

pub fn is_open(&self) -> bool

Check if this record contract is open, meaning that it accepts additional fields to be present, whether the rest is captured or not.

Trait Implementations

impl<'ast> Clone for ArrayPattern<'ast>

fn clone(&self) -> ArrayPattern<'ast>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CloneTo for ArrayPattern<'_>

type Data<'ast> = ArrayPattern<'ast>

This is always Self, be we need associated types to make Rust understand that Self is always parametric over the 'ast lifetime. We’re using GATs to emulate higher-kinded types.

fn clone_to<'to>(data: Self::Data<'_>, dest: &'to AstAlloc) -> Self::Data<'to>

Clones owned data from the current allocator to dest.

impl<'ast> Debug for ArrayPattern<'ast>

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

Formats the value using the given formatter.

impl Display for ArrayPattern<'_>

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

Formats the value using the given formatter.

impl<'ast> FromAst<ArrayPattern<'ast>> for PatternData

fn from_ast(array_pat: &ArrayPattern<'ast>) -> Self

impl<'ast> PartialEq for ArrayPattern<'ast>

fn eq(&self, other: &ArrayPattern<'ast>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'a> Pretty<'a, Allocator> for &ArrayPattern<'_>

fn pretty(self, allocator: &'a Allocator) -> DocBuilder<'a, Allocator>

Converts self into a document

impl Allocable for ArrayPattern<'_>

impl<'ast> Eq for ArrayPattern<'ast>
