Struct PreservationMetadata 

pub struct PreservationMetadata {
    pub requests: BTreeMap<FormatId, Value>,
    pub responses: BTreeMap<FormatId, Value>,
    pub request_seal: Option<u64>,
}

Exact source payloads retained for lossless same-format round trips.

Translation’s default preservation policy prefers a stored same-format body over reconstructing one from normalized fields, which is what makes a same-format hop lossless.

A stored body is only a faithful stand-in while the IR still matches it. LlmRequest::seal_preservation records what the IR looked like when the body was captured, and LlmRequest::preserved_request_is_current reports whether it still does. Callers that mutate the IR — adding a system prompt, appending a handoff note — need do nothing: the seal stops matching and codecs re-encode from normalized fields on their own.

Fields

requests: BTreeMap<FormatId, Value>

Original request bodies keyed by source format.

responses: BTreeMap<FormatId, Value>

Original response bodies keyed by source format.

request_seal: Option<u64>

Fingerprint of the request IR at the moment the bodies above were captured. None means unsealed, which reads as “not current”.

Trait Implementations

impl Clone for PreservationMetadata

fn clone(&self) -> PreservationMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PreservationMetadata

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

Formats the value using the given formatter.

impl Default for PreservationMetadata

fn default() -> PreservationMetadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PreservationMetadata

where PreservationMetadata: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PreservationMetadata

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
