Struct PayloadMeta 

pub struct PayloadMeta {
    pub payload_hash: String,
    pub bytes: u64,
    pub tool_kind: String,
    pub file_roots: Vec<FileRootSerde>,
    pub upstream_keys: Vec<String>,
}

Fields

payload_hash: String

blake3 of the raw payload bytes; recorded so reads can detect a torn write or external file corruption rather than silently returning bad bytes.

bytes: u64

Length of the payload bytes.

tool_kind: String

Tool kind tag, free-form (“read”, “bash”, etc.) — used for telemetry and for tool-specific revalidation logic that the runtime layer applies on green hits.

file_roots: Vec<FileRootSerde>

File dependencies of this entry. Each entry pairs a path with the blake3 of that file at the time the cache entry was written; on every green-hit lookup the file is re-blake3’d and the entry is invalidated on mismatch. Stored on disk so a fresh process can restore the cache state without depending on an in-memory registry that does not survive restart.

upstream_keys: Vec<String>

Upstream cache-key dependencies. For LlmCall entries this is the set of tool-call cache keys whose results appeared in the prompt’s tool_result blocks; when one of those tool entries is invalidated by a file edit, every LlmCall whose upstream set contains that key is invalidated too. Tool-call entries typically leave this empty (their dependencies are encoded in file_roots); future M3+ extensions may use it for nested composite nodes.

Trait Implementations

impl Clone for PayloadMeta

fn clone(&self) -> PayloadMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PayloadMeta

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PayloadMeta

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PayloadMeta

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
