Enum ReplicationFactor

pub enum ReplicationFactor {
    MustReach(usize),
    Range(ReplicationRange),
}

The replication factor of a syncing operation.

Variants

MustReach(usize)

The syncing operation much reach the given value.

See ReplicationFactor::must_reach.

Range(ReplicationRange)

The syncing operation must reach a minimum value, but may continue to reach a maximum value.

See ReplicationFactor::range.

Implementations

impl ReplicationFactor

pub fn range(lower: usize, upper: usize) -> ReplicationFactor

Construct a replication factor with the lower and upper bounds.

If lower >= upper, then ReplicationFactor::MustReach is constructed instead of ReplicationFactor::Range.

pub fn must_reach(factor: usize) -> ReplicationFactor

Construct a replication factor where the factor must be reached.

pub fn lower_bound(&self) -> usize

Get the lower bound of the replication factor.

pub fn upper_bound(&self) -> Option<usize>

Get the upper bound of the replication factor, if the replication factor is a range.

pub fn min(self, new: usize) -> ReplicationFactor

Set the minimum target of the ReplicationFactor to a new value.

If the original value is smaller than the new value, then the original is kept.

If the ReplicationFactor is a range, it performs min on the upper bound of the range.

If self was originally a ReplicationFactor::Range, and min >= max, then the returned value will be ReplicationFactor::MustReach.

Trait Implementations

impl Clone for ReplicationFactor

fn clone(&self) -> ReplicationFactor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReplicationFactor

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

Formats the value using the given formatter.

impl Default for ReplicationFactor

fn default() -> ReplicationFactor

Returns the “default value” for a type.

impl PartialEq for ReplicationFactor

fn eq(&self, other: &ReplicationFactor) -> 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.
