Struct BindingIdentifier 

#[repr(C)]
pub struct BindingIdentifier<'a> {
    pub span: Span,
    pub name: Atom<'a>,
    pub symbol_id: Cell<Option<SymbolId>>,
}

x in const x = 0;

Represents a binding identifier, which is an identifier that is used to declare a variable, function, class, or object.

See: 13.1 Identifiers

Also see other examples in docs for BindingPatternKind.

Fields

span: Span

name: Atom<'a>

The identifier name being bound.

symbol_id: Cell<Option<SymbolId>>

Unique identifier for this binding.

This gets initialized during semantic analysis in the bind step. If you choose to skip semantic analysis, this will always be None.

Implementations

impl BindingIdentifier<'_>

pub fn symbol_id(&self) -> SymbolId

Get SymbolId of BindingIdentifier.

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

Panics

Panics if symbol_id is None.

pub fn set_symbol_id(&self, symbol_id: SymbolId)

Set SymbolId of BindingIdentifier.

Trait Implementations

impl<'a> BoundNames<'a> for BindingIdentifier<'a>

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

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

impl<'a> Clone for BindingIdentifier<'a>

fn clone(&self) -> BindingIdentifier<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

type Cloned = BindingIdentifier<'new_alloc>

The type of the cloned object.

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

fn content_eq(&self, other: &BindingIdentifier<'_>) -> 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 BindingIdentifier<'a>

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

Formats the value using the given formatter.

impl Display for BindingIdentifier<'_>

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for BindingIdentifier<'a>

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

Create a dummy BindingIdentifier.

Does not allocate any data into arena.

impl<'a> GatherNodeParts<'a> for BindingIdentifier<'a>

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

where F: FnMut(&str),

impl Gen for BindingIdentifier<'_>

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 BindingIdentifier<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for BindingIdentifier<'_>

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

impl<'a> TakeIn<'a> for BindingIdentifier<'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 BindingIdentifier<'_>

fn unstable_address(&self) -> Address

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