Struct IdempotencyEntry 

pub struct IdempotencyEntry {
    pub request_body_hash: [u8; 32],
    pub status: u16,
    pub content_type: String,
    pub body: Vec<u8>,
    pub inserted_at: Instant,
}

One cached response entry. Holds enough metadata to project the original wire response back verbatim (status, body, content-type) AND to detect body drift for the same key (request_body_hash).

Fields

request_body_hash: [u8; 32]

SHA-256 of the canonicalized request body. Used to detect “same key, different body” → 422.

status: u16

HTTP status code of the cached response.

content_type: String

Content-Type header of the cached response (preserved verbatim so the replay matches the original wire format — JSON, SSE, ndjson, etc.).

body: Vec<u8>

Cached response body bytes.

inserted_at: Instant

When this entry was inserted. Used by the retention sweep to evict entries older than the configured window.
