Struct N5f1 

pub struct N5f1;

Fault model requiring n >= 5f + 1 participants.

Tolerates up to f = (n-1)/5 faults with quorum size q = n - f (also provided as l_quorum).

Also provides m_quorum which computes 2f + 1.

Example

n	f	quorum (n-f)	m-quorum (2f+1)
6	1	5	3
11	2	9	5
16	3	13	7
21	4	17	9

Implementations

impl N5f1

pub fn m_quorum(n: impl ToPrimitive) -> u32

Compute 2f + 1.

Panics

Panics if n is zero, negative, or exceeds u32::MAX.

pub fn l_quorum(n: impl ToPrimitive) -> u32

Compute n - f.

This is equivalent to Self::quorum.

Panics

Panics if n is zero, negative, or exceeds u32::MAX.

Trait Implementations

impl Clone for N5f1

fn clone(&self) -> N5f1

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for N5f1

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for N5f1

fn default() -> N5f1

Returns the “default value” for a type.

impl Faults for N5f1

fn max_faults(n: impl ToPrimitive) -> u32

Compute the maximum number of faults that can be tolerated for n participants.

fn quorum(n: impl ToPrimitive) -> u32

Compute the quorum size for n participants.

fn quorum_from_slice<T>(slice: &[T]) -> u32

Compute the quorum size from a slice length.

impl PartialEq for N5f1

fn eq(&self, other: &N5f1) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
