Implementations

impl<'a> Declaration<'a>

pub fn is_typescript_syntax(&self) -> bool

Returns true if this declaration uses any TypeScript syntax such as declare, abstract classes, or function overload signatures.

pub fn id(&self) -> Option<&BindingIdentifier<'a>>

Get the identifier bound by this declaration.

Example

const x = 1; // None. may change in the future.
class Foo {} // Some(IdentifierReference { name: "Foo", .. })
enum Bar {} // Some(IdentifierReference { name: "Bar", .. })

pub fn declare(&self) -> bool

Returns true if this declaration was made using the declare keyword in TypeScript.

pub fn is_type(&self) -> bool

Returns true if this declaration is a TypeScript type or interface declaration.

Trait Implementations

impl<'a> BoundNames<'a> for Declaration<'a>

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

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

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

type Cloned = Declaration<'new_alloc>

The type of the cloned object.

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

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

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for Declaration<'a>

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

Create a dummy Declaration.

Has cost of making 1 allocation (40 bytes).

impl<'a> From<Declaration<'a>> for Statement<'a>

fn from(value: Declaration<'a>) -> Statement<'a>

Convert Declaration to Statement.

impl GetAddress for Declaration<'_>

fn address(&self) -> Address

Get the memory address of a value allocated in the arena.

impl GetSpan for Declaration<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for Declaration<'_>

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

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

impl<'a> MayHaveSideEffects<'a> for Declaration<'a>

fn may_have_side_effects( &self, ctx: &impl MayHaveSideEffectsContext<'a>, ) -> bool

impl<'a> TakeIn<'a> for Declaration<'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<'a> TryFrom<Statement<'a>> for Declaration<'a>

fn try_from( value: Statement<'a>, ) -> Result<Declaration<'a>, <Declaration<'a> as TryFrom<Statement<'a>>>::Error>

Convert Statement to Declaration.

type Error = ()

The type returned in the event of a conversion error.
