Struct ProxyContext 

pub struct ProxyContext {
    pub start_time: Instant,
    pub model: Option<String>,
    pub stream_state: Option<StreamState>,
    pub route: RouteInfo,
    pub flags: ConversionFlags,
    pub buffers: ConversionBuffers,
    pub diagnostics: UpstreamDiagnostics,
    pub follow_up: FollowUpContext,
}

Proxy context attached to each request session.

Fields

start_time: Instant

Request start time for duration tracking.

model: Option<String>

Model name parsed from request.

stream_state: Option<StreamState>

Stream state for SSE conversion (also used as a carrier for ResponseRequestContext in non-streaming conversions; this dual use is scheduled to be decoupled in a follow-up commit).

route: RouteInfo

flags: ConversionFlags

buffers: ConversionBuffers

diagnostics: UpstreamDiagnostics

follow_up: FollowUpContext

Implementations

impl ProxyContext

pub fn new() -> Self

Create a new proxy context.

pub fn init_from_response_request(&mut self, req: &ResponseRequest)

Populate model + streaming flags from a parsed ResponseRequest.

Conversion path: callers already deserialize the body as ResponseRequest to perform the conversion, so we accept the parsed struct directly to avoid re-parsing the JSON.

pub fn init_from_passthrough_json(&mut self, json: &Value)

Pass-through path: extract just model + stream from a serde_json::Value.

Used when the body is not a Responses API request (e.g., direct Chat Completions pass-through), so a full typed parse would be wrong.

pub fn set_response_request_context(&mut self, context: ResponseRequestContext)

Set the response request context from a parsed ResponseRequest. This should be called during request_body_filter processing.

Trait Implementations

impl Debug for ProxyContext

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

Formats the value using the given formatter.

impl Default for ProxyContext

fn default() -> Self

Returns the “default value” for a type.
