Represents waitlist managing logic.

Required Associated Types

type Key1

First key type.

type Key2

Second key type.

type Value

Stored values type.

type BlockNumber

Block number type.

Stored with Self::Value.

type Error: WaitlistError

Inner error type of waitlist storing algorithm.

type OutputError: From<Self::Error>

Output error type of the waitlist.

Required Methods

fn contains(key1: &Self::Key1, key2: &Self::Key2) -> bool

Returns bool, defining does first key’s waitlist contain second key.

fn insert( value: Self::Value, bn: Self::BlockNumber ) -> Result<(), Self::OutputError>

Inserts given value in waitlist.

fn remove( key1: Self::Key1, key2: Self::Key2 ) -> Result<(Self::Value, Interval<Self::BlockNumber>), Self::OutputError>

Removes and returns value from waitlist by given keys, if present, else returns error.

fn clear()

Removes all values from all key’s waitlisted.

Object Safety

This trait is not object safe.
