Implementations

impl FunctionExpression

pub fn new( name: Option<Identifier>, parameters: FormalParameterList, body: FunctionBody, linear_span: Option<LinearSpan>, has_binding_identifier: bool, span: Span, ) -> FunctionExpression

Creates a new function expression.

pub const fn name(&self) -> Option<Identifier>

Gets the name of the function expression.

pub const fn parameters(&self) -> &FormalParameterList

Gets the list of parameters of the function expression.

pub const fn body(&self) -> &FunctionBody

Gets the body of the function expression.

pub const fn has_binding_identifier(&self) -> bool

Returns whether the function expression has a binding identifier.

pub const fn name_scope(&self) -> Option<&Scope>

Gets the name scope of the function expression.

pub const fn scopes(&self) -> &FunctionScopes

Gets the scopes of the function expression.

pub const fn linear_span(&self) -> Option<LinearSpan>

Gets linear span of the function declaration.

pub const fn contains_direct_eval(&self) -> bool

Returns true if the function expression contains a direct call to eval.

pub fn analyze_scope( &mut self, strict: bool, scope: &Scope, interner: &Interner, ) -> Result<(), &'static str>

Analyze the scope of the function expression.

Errors

Any scope or binding errors that happened during the analysis.

Trait Implementations

impl Clone for FunctionExpression

fn clone(&self) -> FunctionExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionExpression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl From<FunctionExpression> for Expression

fn from(expr: FunctionExpression) -> Expression

Converts to this type from the input type.

impl PartialEq for FunctionExpression

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

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 FunctionExpression

fn span(&self) -> Span

Returns a span from the current type.

impl ToIndentedString for FunctionExpression

fn to_indented_string(&self, interner: &Interner, indentation: usize) -> String

Converts the element to a string using an interner, with the given indentation.

impl VisitWith for FunctionExpression

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.
