• #a: 1 in class C { #a: 1 } would return None
• 'a': 1 in { 'a': 1 } would return a
• [a]: 1 in { [a]: 1 } would return None

Returns true if the static name of this property key is exactly equal to the given name.

pub fn is_identifier(&self) -> bool

Returns true if this property key is an identifier, such as a in { a: 1 } or #a in class C { #a: 1 }.

pub fn is_private_identifier(&self) -> bool

Returns true if this property key is a private identifier, such as #a in class C { #a: 1 }.

Trait Implementations

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

type Cloned = PropertyKey<'new_alloc>

The type of the cloned object.

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

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