Struct JsSymbol 

pub struct JsSymbol { /* private fields */ }

This represents a JavaScript symbol primitive.

Implementations

impl JsSymbol

pub fn new(description: Option<JsString>) -> Self

Create a new symbol.

pub fn description(&self) -> Option<JsString>

Returns the Symbols description.

pub fn hash(&self) -> u64
