Function mozjs::jsapi::JS::ToBigInt

pub unsafe extern "C" fn ToBigInt(
    cx: *mut JSContext,
    val: Handle<Value>
) -> *mut BigInt

Convert a JS::Value to a BigInt using the ECMAScript ToBigInt algorithm (https://tc39.es/ecma262/#sec-tobigint).

(Note in particular that this will throw if passed a value whose type is ‘number’. To convert a number to a BigInt, use one of the overloads of JS::NumberToBigInt().)
