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

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

Obtain a Cast from a property of the Object.

fn cast_from<T>(&self, prop: &str) -> Result<Cast<'static, T>, Error>

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

fn try_cast_into<T>(&self, prop: &str) -> Result<Option<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 try_cast_from<T>( &self, prop: &str, ) -> Result<Option<Cast<'static, T>>, Error>

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

Get Object property

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

Try Get JsValue property

fn get_string(&self, prop: &str) -> Result<String, Error>

get String property

fn try_get_string(&self, prop: &str) -> Result<Option<String>, Error>

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

get property as Vec<JsValue>

fn get_vec_u8(&self, prop: &str) -> Result<Vec<u8>, Error>

get Vec<u8> property from a hex string or an Array

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>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
