Struct EntryMeta 

pub struct EntryMeta {
    pub cache_key: String,
    pub key_schema: u32,
    pub crate_name: String,
    pub crate_types: Vec<String>,
    pub files: Vec<CachedFile>,
    pub stdout: String,
    pub stderr: String,

Metadata stored alongside cached artifacts.

Fields

cache_key: String

key_schema: u32

Cache-key recipe version that produced cache_key.

Entries written before this field existed deserialize as 0 (unknown), so an explicit stale-schema sweep can reclaim them without making old stores unreadable during an ordinary upgrade.

crate_name: String

crate_types: Vec<String>

files: Vec<CachedFile>

stdout: String

stderr: String

features: Vec<String>

target: String

profile: String

compile_time_ms: u64

emit_kinds: Vec<String>

Canonical rustc --emit kinds this entry actually contains, derived from the stored output files at put time (kunobi-ninja/kache#325). Lookup uses it to reject an entry that doesn’t cover what the invocation’s --emit requested. #[serde(default)] keeps pre-gate meta.json (no field) deserializable — an empty set means “unknown”, so the lookup gate skips the check rather than mass-invalidating old entries.

Implementations

impl EntryMeta

pub fn covers_requested_emit(&self, requested: &[String]) -> bool

Whether this entry’s recorded outputs cover every --emit kind the caller requested (kunobi-ninja/kache#325). Superset-tolerant: an entry that contains more kinds than requested still covers it (a lib --emit=link legitimately also produces .rmeta).

Returns true when emit_kinds is empty — pre-gate entries recorded no coverage, so the check is skipped rather than mass-invalidating them. Requested kinds that map to no stored file class (e.g. an exotic emit kache doesn’t model) are ignored so the gate never rejects on a kind it can’t reason about.
