#[repr(C)]
pub struct ObjectPattern<'a> {
    pub span: Span,
    pub properties: Vec<'a, BindingProperty<'a>>,
    pub rest: Option<Box<'a, BindingRestElement<'a>>>,

{x} in const {x} = 1;.

See other examples in docs for BindingPatternKind.

Fields

span: Span

properties: Vec<'a, BindingProperty<'a>>

rest: Option<Box<'a, BindingRestElement<'a>>>

Implementations

impl ObjectPattern<'_>

pub fn is_empty(&self) -> bool

true for empty object patterns ({}).

pub fn len(&self) -> usize

The number of properties, including rest properties, in this object pattern.

Trait Implementations

impl<'a> BoundNames<'a> for ObjectPattern<'a>

fn bound_names<F>(&self, f: &mut F)

where F: FnMut(&BindingIdentifier<'a>),

impl<'new_alloc> CloneIn<'new_alloc> for ObjectPattern<'_>

type Cloned = ObjectPattern<'new_alloc>

The type of the cloned object.

fn clone_in( &self, allocator: &'new_alloc Allocator, ) -> <ObjectPattern<'_> as CloneIn<'new_alloc>>::Cloned

Clone self into the given allocator. allocator may be the same one that self is already in.

fn clone_in_with_semantic_ids( &self, allocator: &'new_alloc Allocator, ) -> <ObjectPattern<'_> as CloneIn<'new_alloc>>::Cloned

Almost identical as clone_in, but for some special type, it will also clone the semantic ids. Please use this method only if you make sure semantic info is synced with the ast node.

impl ContentEq for ObjectPattern<'_>

fn content_eq(&self, other: &ObjectPattern<'_>) -> bool

This method tests for contents of self and other to be equal.

fn content_ne(&self, other: &Self) -> bool

This method tests for contents of self and other not to be equal. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Debug for ObjectPattern<'a>

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for ObjectPattern<'a>

fn dummy(allocator: &'a Allocator) -> ObjectPattern<'a>

Create a dummy ObjectPattern.

Does not allocate any data into arena.

impl ESTree for ObjectPattern<'_>

fn serialize<S>(&self, serializer: S)

where S: Serializer,

impl<'a> GatherNodeParts<'a> for ObjectPattern<'a>

fn gather<F>(&self, f: &mut F)

where F: FnMut(&str),

impl Gen for ObjectPattern<'_>

fn gen(&self, p: &mut Codegen<'_>, ctx: Context)

Generate code for an AST node.

fn print(&self, p: &mut Codegen<'_>, ctx: Context)

Generate code for an AST node. Alias for gen.

impl GetSpan for ObjectPattern<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for ObjectPattern<'_>

fn span_mut(&mut self) -> &mut Span

Get a mutable reference to an AST node’s Span.

impl<'a> TakeIn<'a> for ObjectPattern<'a>

fn take_in<A>(&mut self, allocator_accessor: A) -> Self

where A: AllocatorAccessor<'a>,

Replace node with a dummy.

fn take_in_box<A>(&mut self, allocator_accessor: A) -> Box<'a, Self>

where A: AllocatorAccessor<'a>,

Replace node with a boxed dummy.
