source

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

source

source§

impl JsUnknown

source

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

source

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

§Safety

This function should be called after JsUnknown::get_type

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