Enum ConsistencyLevel 

#[repr(u8)]
pub enum ConsistencyLevel {
    DcOne = 0,
    DcQuorum = 1,
    DcSafeQuorum = 2,
    DcEachSafeQuorum = 3,
}

Cluster consistency level applied to a single message.

The numeric values match consistency_t in the C reference.

Variants

DcOne = 0

Wait for one replica to ack.

DcQuorum = 1

Wait for a per-DC majority.

DcSafeQuorum = 2

DcQuorum with body checksum agreement; mismatches trigger read repair.

DcEachSafeQuorum = 3

DcSafeQuorum evaluated independently per datacenter.

Implementations

impl ConsistencyLevel

pub fn name(self) -> &'static str

Stable string name.

Examples

use dynomite::msg::ConsistencyLevel;
assert_eq!(ConsistencyLevel::DcQuorum.name(), "DC_QUORUM");

pub fn from_name(name: &str) -> Option<Self>

Recover the level from its uppercase name.

Examples

use dynomite::msg::ConsistencyLevel;
assert_eq!(
    ConsistencyLevel::from_name("DC_SAFE_QUORUM"),
    Some(ConsistencyLevel::DcSafeQuorum),
);

Trait Implementations

impl Clone for ConsistencyLevel

fn clone(&self) -> ConsistencyLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConsistencyLevel

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

Formats the value using the given formatter.

impl Default for ConsistencyLevel

fn default() -> ConsistencyLevel

Returns the “default value” for a type.

impl Hash for ConsistencyLevel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ConsistencyLevel

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