Enum AssignTarget 

pub enum AssignTarget {
    Identifier(Identifier),
    Access(PropertyAccess),
    Pattern(Pattern),
}

The valid left-hand-side expressions of an assignment operator. Also called LeftHandSideExpression in the spec.

Variants

Identifier(Identifier)

A simple identifier, such as a.

Access(PropertyAccess)

A property access, such as a.prop.

Pattern(Pattern)

A pattern assignment, such as {a, b, ...c}.

Implementations

impl AssignTarget

pub fn from_expression( expression: &Expression, strict: bool, ) -> Option<AssignTarget>

Converts the left-hand-side Expression of an assignment expression into an AssignTarget. Returns None if the given Expression is an invalid left-hand-side for a assignment expression.

pub fn from_expression_simple( expression: &Expression, strict: bool, ) -> Option<AssignTarget>

Converts the left-hand-side Expression of an assignment expression into an AssignTarget. Returns None if the given Expression is an invalid left-hand-side for a assignment expression.

The AssignmentTargetType of the expression must be simple.

Trait Implementations

impl Clone for AssignTarget

fn clone(&self) -> AssignTarget

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AssignTarget

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AssignTarget

fn deserialize<__D>( __deserializer: __D, ) -> Result<AssignTarget, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a AssignTarget> for NodeRef<'a>

fn from(node: &'a AssignTarget) -> NodeRef<'a>

Converts to this type from the input type.

impl<'a> From<&'a mut AssignTarget> for NodeRefMut<'a>

fn from(node: &'a mut AssignTarget) -> NodeRefMut<'a>

Converts to this type from the input type.

impl From<Identifier> for AssignTarget

fn from(target: Identifier) -> AssignTarget

Converts to this type from the input type.

impl PartialEq for AssignTarget

fn eq(&self, other: &AssignTarget) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AssignTarget

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spanned for AssignTarget

fn span(&self) -> Span

Returns a span from the current type.

impl ToInternedString for AssignTarget

fn to_interned_string(&self, interner: &Interner) -> String

Converts a given element to a string using an interner.

impl VisitWith for AssignTarget

fn visit_with<'a, V>( &'a self, visitor: &mut V, ) -> ControlFlow<<V as Visitor<'a>>::BreakTy>

where V: Visitor<'a>,

Visit this node with the provided visitor.

fn visit_with_mut<'a, V>( &'a mut self, visitor: &mut V, ) -> ControlFlow<<V as VisitorMut<'a>>::BreakTy>

where V: VisitorMut<'a>,

Visit this node with the provided visitor mutably, allowing the visitor to modify private fields.
