Trait RingBufferMap

pub trait RingBufferMap<Key, Value, QueryKind>
where
    Key: FullCodec,
    Value: FullCodec,
    QueryKind: QueryKindTrait<Value, GetDefault>,
{
    // Required methods
    fn insert(k: Key, v: Value);
    fn contains_key(k: Key) -> bool;
    fn get(k: Key) -> QueryKind::Query;
}

Trait object presenting the ringbuffer interface.

Required Methods

fn insert(k: Key, v: Value)

Insert a map entry.

fn contains_key(k: Key) -> bool

Check if map contains a key

fn get(k: Key) -> QueryKind::Query

Get the value of the key

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.
