Struct FunctionExpr

pub struct FunctionExpr { /* private fields */ }

The function expression defines a function with the specified parameters.

A function created with a function expression is a Function object and has all the properties, methods and behavior of Function.

A function can also be created using a declaration (see function expression).

By default, functions return undefined. To return any other value, the function must have a return statement that specifies the value to return.

• ECMAScript reference
• MDN documentation

Implementations

impl FunctionExpr

pub fn name(&self) -> Option<&str>

Gets the name of the function declaration.

pub fn parameters(&self) -> &[FormalParameter]

Gets the list of parameters of the function declaration.

pub fn body(&self) -> &StatementList

Gets the body of the function declaration.

Trait Implementations

impl Clone for FunctionExpr

fn clone(&self) -> FunctionExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionExpr

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

Formats the value using the given formatter.

impl Display for FunctionExpr

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

Formats the value using the given formatter.

impl Drop for FunctionExpr

fn drop(&mut self)

Executes the destructor for this type.

impl Executable for FunctionExpr

fn run(&self, context: &mut Context) -> JsResult<JsValue>

Runs this executable in the given context.

impl Finalize for FunctionExpr

fn finalize(&self)

impl From<FunctionExpr> for Node

fn from(expr: FunctionExpr) -> Self

Converts to this type from the input type.

impl PartialEq for FunctionExpr

fn eq(&self, other: &FunctionExpr) -> 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 Trace for FunctionExpr

unsafe fn trace(&self)

Marks all contained Gcs.

unsafe fn root(&self)

Increments the root-count of all contained Gcs.

unsafe fn unroot(&self)

Decrements the root-count of all contained Gcs.

fn finalize_glue(&self)

Runs Finalize::finalize() on this object and all contained subobjects
