Fields

span: Span

decorators: Vec<'a, Decorator<'a>>

Decorators applied to the property.

See Decorator for more information.

key: PropertyKey<'a>

The expression used to declare the property.

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

Type annotation on the property.

e.g. class Foo { x: number; }

Will only ever be Some for TypeScript files.

value: Option<Expression<'a>>

Initialized value in the declaration.

Example

class Foo {
  x = 5;     // Some(NumericLiteral)
  y;         // None
  z: string; // None

  constructor() {
    this.z = "hello";
  }
}

type: PropertyDefinitionType

computed: bool

Property was declared with a computed key

Example

class Foo {
  ["a"]: 1; // true
  b: 2;     // false
}

static: bool

Property was declared with a static modifier

declare: bool

Property is declared with a declare modifier.

Example

class Foo {
  x: number;         // false
  declare y: string; // true
}

declare class Bar {
  x: number;         // false
}

override: bool

optional: bool

true when created with an optional modifier (?)

definite: bool

readonly: bool

true when declared with a readonly modifier

accessibility: Option<TSAccessibility>

Accessibility modifier.

Only ever Some for TypeScript files.

Example

class Foo {
  public w: number;     // Some(TSAccessibility::Public)
  private x: string;    // Some(TSAccessibility::Private)
  protected y: boolean; // Some(TSAccessibility::Protected)
  readonly z;           // None
}

Trait Implementations

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

type Cloned = PropertyDefinition<'new_alloc>

The type of the cloned object.

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

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

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for PropertyDefinition<'a>

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

Create a dummy PropertyDefinition.

Has cost of making 1 allocation (8 bytes).

impl<'a> GatherNodeParts<'a> for PropertyDefinition<'a>

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

where F: FnMut(&str),

impl Gen for PropertyDefinition<'_>

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 PropertyDefinition<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for PropertyDefinition<'_>

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

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

impl PrivateBoundIdentifiers for PropertyDefinition<'_>

fn private_bound_identifiers(&self) -> Option<PrivateIdentifier<'_>>

impl PropName for PropertyDefinition<'_>

fn prop_name(&self) -> Option<(&str, Span)>

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

fn unstable_address(&self) -> Address

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