Trait to be implemented by a Rust struct representation of an on-chain config that is stored in storage as a serialized byte array

Required Associated Constants

const IDENTIFIER: &'static str

Provided Associated Constants

const ADDRESS: &'static str = CONFIG_ADDRESS_STR

const CONFIG_ID: ConfigID = _

Provided Methods

fn deserialize_default_impl(bytes: &[u8]) -> Result<Self>

fn deserialize_into_config(bytes: &[u8]) -> Result<Self>

fn fetch_config<T>(storage: &T) -> Option<Self>

where T: ConfigStorage,

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.
