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

Implementations

impl JsUnknown

pub fn into_unknown(self) -> JsUnknown

pub fn coerce_to_bool(self) -> Result<JsBoolean>

pub fn coerce_to_number(self) -> Result<JsNumber>

pub fn coerce_to_string(self) -> Result<JsString>

pub fn coerce_to_object(self) -> Result<JsObject>

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

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

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

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

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

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

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

pub fn instanceof<Constructor>(&self, constructor: Constructor) -> Result<bool>

where Constructor: NapiRaw,

impl JsUnknown

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

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
