Implementations

impl FunctionExpression

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

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.
