Struct TranslationEngine 

pub struct TranslationEngine { /* private fields */ }

Stateless request/response translator that routes through the neutral IR.

Implementations

impl TranslationEngine

pub fn new(registry: FormatRegistry) -> Self

Creates an engine from an explicit buffered codec registry.

pub fn with_registries( registry: FormatRegistry, stream_registry: StreamCodecRegistry, ) -> Self

Creates an engine from explicit buffered and streaming codec registries.

pub fn decode_request( &self, source: impl Into<FormatId>, body: &Value, policy: &TranslationPolicy, ) -> Result<RequestIrOutput>

Decodes a request body into the neutral request IR.

pub fn encode_request( &self, target: impl Into<FormatId>, request: &LlmRequest, policy: &TranslationPolicy, ) -> Result<TranslationOutput>

Encodes a neutral request IR into a target wire format.

pub fn translate_request( &self, source: impl Into<FormatId>, target: impl Into<FormatId>, body: &Value, policy: &TranslationPolicy, ) -> Result<TranslationOutput>

Translates a request body from source format to target format.

pub fn decode_response( &self, source: impl Into<FormatId>, body: &Value, policy: &TranslationPolicy, ) -> Result<ResponseIrOutput>

Decodes a response body into the neutral response IR.

pub fn encode_response( &self, target: impl Into<FormatId>, response: &AggLlmResponse, policy: &TranslationPolicy, ) -> Result<TranslationOutput>

Encodes a neutral response IR into a target wire format.

pub fn translate_response( &self, source: impl Into<FormatId>, target: impl Into<FormatId>, body: &Value, policy: &TranslationPolicy, ) -> Result<TranslationOutput>

Translates a response body from source format to target format.

pub fn translate_event( &self, state: &mut StreamTranslationState, source: impl Into<FormatId>, target: impl Into<FormatId>, event: &Value, ) -> Result<Vec<Value>>

Translates one streaming source event into zero or more target events.

pub fn decode_stream_event( &self, state: &mut StreamTranslationState, source: impl Into<FormatId>, event: Value, ) -> Result<LlmResponseStreamEvent>

Decodes one provider event while retaining its parsed source JSON value.

Takes ownership of event so preservation does not deep-copy provider JSON on the per-event streaming path.

pub fn encode_stream_event( &self, state: &mut StreamTranslationState, target: impl Into<FormatId>, event: LlmResponseStreamEvent, ) -> Result<Vec<Value>>

Encodes one neutral or preserved stream event for a target provider.

A preserved event replays its retained JSON value unchanged when its source and target formats match. Cross-format encoding intentionally uses only its normalized events.

pub fn finish_stream( &self, state: &mut StreamTranslationState, target: impl Into<FormatId>, ) -> Result<Vec<Value>>

Finishes target-provider stream emission after the source stream closes.

Trait Implementations

impl Default for TranslationEngine

fn default() -> Self

Returns the “default value” for a type.
