Struct VariableDeclarator 

#[non_exhaustive]
#[repr(C)]
pub struct VariableDeclarator<'a> {
    pub node_id: Cell<NodeId>,
    pub span: Span,
    pub kind: VariableDeclarationKind,
    pub id: BindingPattern<'a>,
    pub type_annotation: Option<Box<'a, TSTypeAnnotation<'a>>>,
    pub init: Option<Expression<'a>>,
    pub definite: bool,
}

A single variable declaration in a list of variable declarations.

Examples

// declarators may or may not have initializers
let foo, b = 1;
//  ^^^ id   ^ init

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

node_id: Cell<NodeId>

span: Span

kind: VariableDeclarationKind

id: BindingPattern<'a>

type_annotation: Option<Box<'a, TSTypeAnnotation<'a>>>

init: Option<Expression<'a>>

definite: bool

Implementations

impl VariableDeclarator<'_>

pub fn node_id(&self) -> NodeId

Get NodeId of VariableDeclarator.

Only use this method on a post-semantic AST where NodeIds are always defined.

pub fn set_node_id(&self, node_id: NodeId)

Set NodeId of VariableDeclarator.

Trait Implementations

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

type Cloned = VariableDeclarator<'new_alloc>

The type of the cloned object.

fn clone_in(&self, allocator: &'new_alloc Allocator) -> Self::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, ) -> Self::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 VariableDeclarator<'_>

fn content_eq(&self, other: &Self) -> 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 VariableDeclarator<'a>

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for VariableDeclarator<'a>

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

Create a dummy VariableDeclarator.

Has cost of making 1 allocation (32 bytes).

impl GetSpan for VariableDeclarator<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for VariableDeclarator<'_>

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

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

impl<'a> TakeIn<'a> for VariableDeclarator<'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.

impl UnstableAddress for VariableDeclarator<'_>

fn unstable_address(&self) -> Address

Get the memory Address of a reference to an AST node in arena, which is not necessarily stable.
