Enum ServerOrderingStrategy

#[non_exhaustive]
pub enum ServerOrderingStrategy {
    QueryStatistics,
    UserProvidedOrder,
    RoundRobin,
}

The strategy for establishing the query order of name servers in a pool.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

QueryStatistics

Servers are ordered based on collected query statistics. The ordering may vary over time.

UserProvidedOrder

The order provided to the resolver is used. The ordering does not vary over time.

RoundRobin

The order of servers is rotated in a round-robin fashion. This is useful for load balancing and ensuring that all servers are used evenly.

Trait Implementations

impl Clone for ServerOrderingStrategy

fn clone(&self) -> ServerOrderingStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ServerOrderingStrategy

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

Formats the value using the given formatter.

impl Default for ServerOrderingStrategy

fn default() -> Self

Returns ServerOrderingStrategy::QueryStatistics as the default.

impl<'de> Deserialize<'de> for ServerOrderingStrategy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ServerOrderingStrategy

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

impl Serialize for ServerOrderingStrategy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
