Implementations

impl JsUnknown[src]

pub fn into_unknown(self) -> JsUnknown[src]

pub fn coerce_to_number(self) -> Result<JsNumber>[src]

pub fn coerce_to_string(self) -> Result<JsString>[src]

pub fn coerce_to_object(self) -> Result<JsObject>[src]

pub fn is_date(&self) -> Result<bool>[src]

pub fn is_promise(&self) -> Result<bool>[src]

pub fn is_error(&self) -> Result<bool>[src]

pub fn is_typedarray(&self) -> Result<bool>[src]

pub fn is_dataview(&self) -> Result<bool>[src]

pub fn is_array(&self) -> Result<bool>[src]

pub fn is_buffer(&self) -> Result<bool>[src]

pub fn instanceof<Constructor>(&self, constructor: Constructor) -> Result<bool> where
    Constructor: NapiRaw, [src]

pub fn freeze(&mut self) -> Result<()>[src]

pub fn seal(&mut self) -> Result<()>[src]

impl JsUnknown[src]

pub fn get_type(&self) -> Result<ValueType>[src]

pub unsafe fn cast<V>(&self) -> V where
    V: NapiValue, [src]

Safety

This function should be called after JsUnknown::get_type

And the V must be match with the return value of get_type
