Enum ConsistencyLevel 

pub enum ConsistencyLevel {
    DcOne,
    DcQuorum,
    DcSafeQuorum,
    DcEachSafeQuorum,
}

Quorum policy for read or write paths.

Examples

use dynomite::conf::ConsistencyLevel;
let lvl = ConsistencyLevel::parse("read_consistency", "DC_QUORUM").unwrap();
assert_eq!(lvl, ConsistencyLevel::DcQuorum);

Variants

DcOne

Single replica acknowledgement.

DcQuorum

Majority within a single datacenter.

DcSafeQuorum

Majority within a single datacenter with checksum repair.

DcEachSafeQuorum

Majority within every datacenter, with checksum repair.

Implementations

impl ConsistencyLevel

pub fn parse(field: &'static str, s: &str) -> Result<Self, ConfError>

Parse a read_consistency or write_consistency value.

Comparison is case-insensitive against the canonical names DC_ONE, DC_QUORUM, DC_SAFE_QUORUM, and DC_EACH_SAFE_QUORUM.

Examples

use dynomite::conf::ConsistencyLevel;
assert_eq!(
    ConsistencyLevel::parse("read_consistency", "dc_one").unwrap(),
    ConsistencyLevel::DcOne,
);
assert!(ConsistencyLevel::parse("read_consistency", "nope").is_err());

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

Render back to the canonical YAML name.

Examples

use dynomite::conf::ConsistencyLevel;
assert_eq!(ConsistencyLevel::DcSafeQuorum.as_str(), "DC_SAFE_QUORUM");

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 Display for ConsistencyLevel

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

Formats the value using the given formatter.

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.
