Enum ProviderType 

pub enum ProviderType {
    OpenAI,
    XAI,
    Anthropic,
    Gemini,
    Custom(String),
}

Provider type for external API transformations.

Different providers have different API formats and requirements. None (when used as Option<ProviderType>) means native/passthrough — no transformation needed (local SGLang backends).

Variants

OpenAI

OpenAI API — strip SGLang-specific fields.

XAI

xAI/Grok — special handling for input items.

Anthropic

Anthropic Claude — different API format.

Gemini

Google Gemini — special logprobs handling.

Custom(String)

Custom provider with string identifier.

Implementations

impl ProviderType

pub fn as_str(&self) -> &str

Get provider name as string.

pub fn from_url(url: &str) -> Option<Self>

Detect provider from URL host. Returns None for URLs that don’t match known providers or can’t be parsed.

pub fn admin_key_env_var(&self) -> Option<&'static str>

Environment variable name for per-provider admin API key (model discovery). Returns None for Custom providers since there’s no known env var.

pub fn uses_x_api_key(&self) -> bool

Whether this provider uses x-api-key header instead of Authorization: Bearer.

pub fn from_model_name(model: &str) -> Option<Self>

Detect provider from model name (heuristic fallback). Returns None for models that don’t match known external providers.

Trait Implementations

impl Clone for ProviderType

fn clone(&self) -> ProviderType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProviderType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProviderType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProviderType

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

Formats the value using the given formatter.

impl Hash for ProviderType

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 JsonSchema for ProviderType

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for ProviderType

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
