Struct Identifier

pub struct Identifier { /* private fields */ }

An identifier is a sequence of characters in the code that identifies a variable, function, or property.

In JavaScript, identifiers are case-sensitive and can contain Unicode letters, $, _, and digits (0-9), but may not start with a digit.

An identifier differs from a string in that a string is data, while an identifier is part of the code. In JavaScript, there is no way to convert identifiers to strings, but sometimes it is possible to parse strings into identifiers.

Trait Implementations

impl AsRef<str> for Identifier

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Identifier

fn clone(&self) -> Identifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Identifier

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

Formats the value using the given formatter.

impl Display for Identifier

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

Formats the value using the given formatter.

impl Drop for Identifier

fn drop(&mut self)

Executes the destructor for this type.

impl Executable for Identifier

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

Runs this executable in the given context.

impl Finalize for Identifier

fn finalize(&self)

impl From<Identifier> for Node

fn from(local: Identifier) -> Self

Converts to this type from the input type.

impl<T> From<T> for Identifier

where T: Into<Box<str>>,

fn from(stm: T) -> Self

Converts to this type from the input type.

impl PartialEq for Identifier

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

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
