impl ArrayExpressionElement<'_>

pub fn is_elision(&self) -> bool

Returns true if this array expression element is an elision. An elision is a comma in an array literal that is not followed by an expression. For example, in [1, , 3], the second element is an elision.

pub fn is_spread(&self) -> bool

Returns true if this array expression element is a spread.

Trait Implementations

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

type Cloned = ArrayExpressionElement<'new_alloc>

The type of the cloned object.

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

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

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for ArrayExpressionElement<'a>

impl<'a> From<MemberExpression<'a>> for ArrayExpressionElement<'a>

fn from(value: MemberExpression<'a>) -> ArrayExpressionElement<'a>

Convert MemberExpression to ArrayExpressionElement.

impl Gen for ArrayExpressionElement<'_>
