Trait frame_support::traits::Instance

pub trait Instance: 'static {
    const PREFIX: &'static str;
    const INDEX: u8;
}

An instance of a pallet in the storage.

It is required that these instances are unique, to support multiple instances per pallet in the same runtime!

E.g. for module MyModule default instance will have prefix “MyModule” and other instances “InstanceNMyModule”.

Required Associated Constants

const PREFIX: &'static str

Unique module prefix. E.g. “InstanceNMyModule” or “MyModule”

const INDEX: u8

Unique numerical identifier for an instance.

Object Safety

This trait is not object safe.
