Struct IdentifierReference 

#[repr(C)]
pub struct IdentifierReference<'a> {
    pub span: Span,
    pub name: Atom<'a>,
    pub reference_id: Cell<Option<ReferenceId>>,
}

x inside func in const x = 0; function func() { console.log(x); }

Represents an identifier reference, which is a reference to a variable, function, class, or object.

See: 13.1 Identifiers

Fields

span: Span

name: Atom<'a>

The name of the identifier being referenced.

reference_id: Cell<Option<ReferenceId>>

Reference ID

Identifies what identifier this refers to, and how it is used. This is set in the bind step of semantic analysis, and will always be None immediately after parsing.

Implementations

impl IdentifierReference<'_>

pub fn reference_id(&self) -> ReferenceId

Get ReferenceId of IdentifierReference.

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

Panics

Panics if reference_id is None.

pub fn set_reference_id(&self, reference_id: ReferenceId)

Set ReferenceId of IdentifierReference.

Trait Implementations

impl<'a> Clone for IdentifierReference<'a>

fn clone(&self) -> IdentifierReference<'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 IdentifierReference<'_>

type Cloned = IdentifierReference<'new_alloc>

The type of the cloned object.

fn clone_in( &self, allocator: &'new_alloc Allocator, ) -> <IdentifierReference<'_> 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, ) -> <IdentifierReference<'_> 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<'a> ConstantEvaluation<'a> for IdentifierReference<'a>

fn evaluate_value_to( &self, ctx: &impl ConstantEvaluationCtx<'a>, _target_ty: Option<ValueType>, ) -> Option<ConstantValue<'a>>

Evaluate the expression to a constant value.

fn evaluate_value( &self, ctx: &impl ConstantEvaluationCtx<'a>, ) -> Option<ConstantValue<'a>>

Evaluate the expression to a constant value.

fn evaluate_value_to_number( &self, ctx: &impl ConstantEvaluationCtx<'a>, ) -> Option<f64>

Evaluate the expression to a constant value and convert it to a number.

fn evaluate_value_to_bigint( &self, ctx: &impl ConstantEvaluationCtx<'a>, ) -> Option<BigInt>

Evaluate the expression to a constant value and convert it to a bigint.

fn evaluate_value_to_boolean( &self, ctx: &impl ConstantEvaluationCtx<'a>, ) -> Option<bool>

Evaluate the expression to a constant value and convert it to a boolean.

fn evaluate_value_to_string( &self, ctx: &impl ConstantEvaluationCtx<'a>, ) -> Option<Cow<'a, str>>

Evaluate the expression to a constant value and convert it to a string.

fn get_side_free_number_value( &self, ctx: &impl ConstantEvaluationCtx<'a>, ) -> Option<f64>

impl ContentEq for IdentifierReference<'_>

fn content_eq(&self, other: &IdentifierReference<'_>) -> 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.
