Implementations

impl JSValueRef

pub fn get_tag(&self) -> i64

pub fn new_no_context(value: JSValue, label: &str) -> Self

pub fn new(
    context: *mut JSContext,
    value: JSValue,

pub fn is_big_int(&self) -> bool

pub fn is_exception(&self) -> bool

return true if the wrapped value represents a JS Exception value

pub fn is_object(&self) -> bool

return true if the wrapped value represents a JS Object value

pub fn is_string(&self) -> bool
