Struct ResponseContext 

pub struct ResponseContext {
    pub status: u16,
    pub headers: HeaderMap,
    pub body: Vec<u8>,
    pub was_sse: bool,
    pub json: Option<Value>,
    pub rpc_error: Option<(i64, String)>,
    pub upstream_us: Option<u64>,
}

Response-side state threaded through the response middleware chain.

Middleware mutate body and json in place. Handlers instantiate after reading the upstream body and finalize by building an axum::Response from (status, headers, body).

Fields

status: u16

headers: HeaderMap

body: Vec<u8>

Serialized response body — what gets returned to the client. Mutated by the rewrite and SSE-wrap middleware.

was_sse: bool

True when the upstream sent SSE-wrapped JSON. SseUnwrapMiddleware sets it; SseWrapMiddleware reads it to decide whether to re-wrap.

json: Option<Value>

Parsed JSON view of the body. Populated by SseUnwrapMiddleware; mutated by later middleware; serialized back into body by SseWrapMiddleware.

rpc_error: Option<(i64, String)>

JSON-RPC error extracted from json (when present).

upstream_us: Option<u64>
