Struct PropertyKey 

pub struct PropertyKey(/* private fields */);

A property key: a string, an array index or a symbol. Made by Runtime::intern_property_key or from a SymbolRef.

Implementations

impl PropertyKey

pub fn try_clone(&self) -> Result<Self, RuntimeError>

pub fn from_js_string(text: JsString) -> Self

The key of the string text (an index when text is one’s canonical form, as ToPropertyKey reads it).

pub fn index(index: u32) -> Self

pub fn as_symbol(&self) -> Option<&SymbolRef>

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

The key as a string; None for a symbol.
