Implementations

impl<'a> ChainElement<'a>

pub fn is_member_expression(&self) -> bool

Return if a ChainElement is a MemberExpression.

pub fn into_member_expression(self) -> MemberExpression<'a>

Convert ChainElement to MemberExpression.

Panic

Panics if not convertible.

pub fn as_member_expression(&self) -> Option<&MemberExpression<'a>>

Convert &ChainElement to &MemberExpression.

pub fn as_member_expression_mut(&mut self) -> Option<&mut MemberExpression<'a>>

Convert &mut ChainElement to &mut MemberExpression.

pub fn to_member_expression(&self) -> &MemberExpression<'a>

Convert &ChainElement to &MemberExpression.

Panic

Panics if not convertible.

pub fn to_member_expression_mut(&mut self) -> &mut MemberExpression<'a>

Convert &mut ChainElement to &mut MemberExpression.

Panic

Panics if not convertible.

impl<'a> ChainElement<'a>

pub fn member_expression(&self) -> Option<&MemberExpression<'a>>

Returns the member expression.

Trait Implementations

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

type Cloned = ChainElement<'new_alloc>

The type of the cloned object.

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

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

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

Formats the value using the given formatter.

impl<'a> Dummy<'a> for ChainElement<'a>

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

Create a dummy ChainElement.

Has cost of making 2 allocations (32 bytes).

impl<'a> From<ChainElement<'a>> for Expression<'a>

fn from(value: ChainElement<'a>) -> Expression<'a>

Converts to this type from the input type.

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

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

Convert MemberExpression to ChainElement.

impl GetAddress for ChainElement<'_>

fn address(&self) -> Address

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

impl GetSpan for ChainElement<'_>

fn span(&self) -> Span

Get the Span for an AST node.

impl GetSpanMut for ChainElement<'_>

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

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

impl<'a> MayHaveSideEffects<'a> for ChainElement<'a>

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

impl<'a> TakeIn<'a> for ChainElement<'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<ChainElement<'a>> for MemberExpression<'a>

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

Convert ChainElement to MemberExpression.

type Error = ()

The type returned in the event of a conversion error.
