Struct FormalParameter

pub struct FormalParameter { /* private fields */ }

“Formal parameter” is a fancy way of saying “function parameter”.

In the declaration of a function, the parameters must be identifiers, not any value like numbers, strings, or objects.

function foo(formalParameter1, formalParameter2) {
}

Implementations

impl FormalParameter

pub fn name(&self) -> &str

Gets the name of the formal parameter.

pub fn init(&self) -> Option<&Node>

Gets the initialization node of the formal parameter, if any.

pub fn is_rest_param(&self) -> bool

Gets wether the parameter is a rest parameter.

Trait Implementations

impl Clone for FormalParameter

fn clone(&self) -> FormalParameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormalParameter

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

Formats the value using the given formatter.

impl Display for FormalParameter

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

Formats the value using the given formatter.

impl Drop for FormalParameter

fn drop(&mut self)

Executes the destructor for this type.

impl Finalize for FormalParameter

fn finalize(&self)

impl PartialEq for FormalParameter

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

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
