Struct boa::JsSymbol

pub struct JsSymbol { /* fields omitted */ }

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

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<JsSymbol> for JsSymbol

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
