Struct napi::bindgen_prelude::Unknown

source · [−]

pub struct Unknown(_);

Implementations

source

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

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
