Struct Break 

pub struct Break { /* private fields */ }

The break statement terminates the current loop, switch, or label statement and transfers program control to the statement following the terminated statement.

The break statement includes an optional label that allows the program to break out of a labeled statement. The break statement needs to be nested within the referenced label. The labeled statement can be any block statement; it does not have to be preceded by a loop statement.

More information:

• ECMAScript reference
• MDN documentation

Implementations

impl Break

pub const fn new(label: Option<Sym>) -> Break

Creates a Break AST node.

pub const fn label(&self) -> Option<Sym>

Gets the label of the break statement, if any.

Trait Implementations

impl Clone for Break

fn clone(&self) -> Break

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Break

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Break

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl From<Break> for Statement

fn from(break_smt: Break) -> Statement

Converts to this type from the input type.

impl PartialEq for Break

fn eq(&self, other: &Break) -> 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 Break

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 ToInternedString for Break

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

Converts a given element to a string using an interner.

impl VisitWith for Break

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.

impl Copy for Break

impl Eq for Break

impl StructuralPartialEq for Break
