Struct InMemoryStorage 

pub struct InMemoryStorage { /* private fields */ }

An in-memory SaveStorage implementation backed by Vec<Option<Vec<u8>>>.

Intended for use in tests and as a reference implementation.

Implementations

impl InMemoryStorage

pub fn new() -> Self

Create a new in-memory storage with 3 empty slots.
