Enum TierSelectionStrategy 

#[non_exhaustive]
pub enum TierSelectionStrategy {
    PreferenceOrder,
    RoundRobin,
    LowestCost,
    Random,
}

Strategy for selecting a model within a tier.

Controls how the router picks among multiple models in a single tier. Serializes/deserializes as snake_case strings (e.g., "preference_order").

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.

PreferenceOrder

Use models in the order listed (first available wins).

RoundRobin

Rotate through models in round-robin fashion.

LowestCost

Pick the cheapest model in the tier.

Random

Pick a random model from the tier.

Trait Implementations

impl Clone for TierSelectionStrategy

fn clone(&self) -> TierSelectionStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TierSelectionStrategy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TierSelectionStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TierSelectionStrategy

fn eq(&self, other: &TierSelectionStrategy) -> 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 TierSelectionStrategy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
