Fields

schema_version_before: u32

schema_version_after: u32

migration_steps: Vec<MigrationStepReport>

embedder_warmup_ms: u64

query_backend: &'static str

default_embedder: EmbedderIdentity

embedder_download_ms: Option<u64>

Total wall time the loader spent materializing default-embedder weights — covers HF GETs, sha256 verification, atomic rename, parent-dir fsync (POSIX), and cache directory writes. This is the “engine open paid by the embedder” envelope, useful for SLA budgeting; it is intentionally wider than just the bytes-flowing time so callers see the full first-use cost.

Some(ms) when network bytes flowed (bytes_downloaded > 0); None for caller-supplied embedders (loader bypassed) and on full cache hits (no bytes flowed). For pure per-file network analysis, use the DefaultEmbedderDownload events on embedder_events — each event carries the file’s bytes + sha256 + cache path.

embedder_events: Vec<EmbedderEvent>

Structured loader events (dev/design/embedder.md §7). Empty for caller-supplied embedders; populated from LoadedWeights.events for the Default path.

embedder_mean_centering_required: bool

Static identity capability (dev/design/embedder.md §0.6). True iff the live embedder identity is the bge-small default, which is the only identity that ships with the EU-5a2 mean-centering apply paths. false for fathomdb-noop and for any other caller-supplied identity. EU-5b’s identity flip makes the Default path return true here.

embedder_mean_vec_pinned: bool

Dynamic workspace state (dev/design/embedder.md §0.6). True iff _fathomdb_embedder_profiles.mean_vec IS NOT NULL for the default profile. EU-5a2 reads from the schema column added in migration step 10; the value is dimension-validated (§0.2) at open time and fails closed via EmbedderIdentityMismatch on drift.

Trait Implementations

impl Clone for OpenReport

fn clone(&self) -> OpenReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpenReport

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

Formats the value using the given formatter.

impl Eq for OpenReport

impl PartialEq for OpenReport

fn eq(&self, other: &OpenReport) -> 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.
