Custom trait implementing simplified property accessor functions for Object.

Required Methods

fn get<T>(&self, prop: &str) -> Result<T, Error>

where T: TryFrom<JsValue>, <T as TryFrom<JsValue>>::Error: Display,

Get a type that implements TryFrom<JsValue> from a property of the Object.

fn try_get<T>(&self, prop: &str) -> Result<Option<T>, Error>

where T: TryFrom<JsValue>, <T as TryFrom<JsValue>>::Error: Display,

Try to get a type that implements TryFrom<JsValue> from a property of the Object. Returns Ok(None) if the property does not exist.

fn get_cast<T>(&self, prop: &str) -> Result<Cast<T>, Error>

where T: TryCastFromJs, <T as TryCastFromJs>::Error: Display,

Obtain a Cast from a property of the Object.

fn try_get_cast<T>(&self, prop: &str) -> Result<Option<Cast<T>>, Error>

where T: TryCastFromJs, <T as TryCastFromJs>::Error: Display,

Try to obtain a Cast from a property of the Object. Returns Ok(None) if the property does not exist (null or undefined).

fn get_value(&self, prop: &str) -> Result<JsValue, Error>

Get JsValue property

fn get_object(&self, prop: &str) -> Result<Object, Error>

fn get_vec_u8_from_number_array(&self, prop: &str) -> Result<Vec<u8>, Error>

get Uint8Array property as Vec<u8>

fn get_vec_u8_from_uint8_array(&self, prop: &str) -> Result<Vec<u8>, Error>
