Enum ServiceTier 

#[non_exhaustive]
pub enum ServiceTier {
    Auto,
    Default,
    Flex,
    Priority,
    Scale,
}

OpenAI service-tier routing — cost / latency knob shared by both Chat Completions and Responses APIs. OpenAI-specific (no other vendor exposes a comparable per-request routing channel).

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.

Auto

Vendor picks the tier (default behaviour when the field is omitted; supplying Auto makes the choice explicit).

Default

Standard processing tier — vendor’s default capacity pool.

Flex

Cheaper async tier with relaxed latency SLO (~50% cost cut).

Priority

Reserved-capacity tier for latency-bound enterprise workflows.

Scale

High-throughput sustained-traffic tier.

Trait Implementations

impl Clone for ServiceTier

fn clone(&self) -> ServiceTier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceTier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServiceTier

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ServiceTier

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
