Fields

request: String

The request line.

outcome: &'static str

planned (served from the index), fallback (full descriptor read), or declined (the observation itself declined).

fallback_reason: String

Why a fallback happened, when it did.

units_read: usize

Units fetched by the coarse source.

preads: u64

Real pread calls made by the coarse source.

unit_bytes: u64

Real descriptor payload bytes fetched by the coarse source.

covered: Option<(u64, u64)>

The covered source span, if any.

manifest_bytes: u64

Manifest bytes the observation fetched.

index_bytes: u64

Hierarchical-index bytes the observation fetched.

seed_bytes: u64

Seed bytes the observation fetched.

dir_bytes: u64

Persisted index file size (the directory the read pays).

closure_bytes: u64

Honest total physical bytes for this lane.

answer_bytes: u64

Bytes returned by the observation.

matches_full: bool

Whether the answer matched the full-read answer.
