Trait Quorum 

pub trait Quorum {
    type Item: Ord;

    // Required methods
    fn quorum<M: Faults>(&self) -> u32;
    fn max_faults<M: Faults>(&self) -> u32;
    fn key(&self, index: Participant) -> Option<&Self::Item>;
    fn index(&self, key: &Self::Item) -> Option<Participant>;
}

Extension trait for Set participant sets providing quorum and index utilities.

Required Associated Types

type Item: Ord

The type of items in this set.

Required Methods

fn quorum<M: Faults>(&self) -> u32

Returns the quorum value for this participant set using the given fault model.

Panics

Panics if the number of participants exceeds u32::MAX.

fn max_faults<M: Faults>(&self) -> u32

Returns the maximum number of faults tolerated by this participant set.

Panics

Panics if the number of participants exceeds u32::MAX.

fn key(&self, index: Participant) -> Option<&Self::Item>

Returns the participant key at the given index.

fn index(&self, key: &Self::Item) -> Option<Participant>

Returns the index for the given participant key, if present.

Panics

Panics if the participant index exceeds u32::MAX.

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.
