Enum LetPattern 

pub enum LetPattern {
    Ident(Ident),
    Wildcard(Span),
    Struct {
        type_name: Ident,
        fields: Vec<DestructureField>,
        span: Span,
    },
}

A pattern in a let binding.

Variants

Ident(Ident)

Named binding (e.g., x, _unused)

Wildcard(Span)

Wildcard pattern _ - discards the value without creating a binding

Struct

Struct destructuring (e.g., Point { x, y })

Fields

type_name: Ident

fields: Vec<DestructureField>

span: Span

Implementations

impl LetPattern

pub fn span(&self) -> Span

Get the span of this pattern.

Trait Implementations

impl Clone for LetPattern

fn clone(&self) -> LetPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LetPattern

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

Formats the value using the given formatter.

impl PartialEq for LetPattern

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