Struct EmitReport 

pub struct EmitReport {
    pub written: u32,
    pub copied: u32,
    pub recompressed: u32,
    pub deltified: u32,
    pub rebased: u32,
    pub bytes: u64,
}

What emitting produced, in facts a caller can assert on.

Fields

written: u32

Entries written.

copied: u32

Entries whose stored payload was copied unchanged. It is counted rather than assumed because “correct but slow” is the failure index-pack --strict and fsck both pass.

recompressed: u32

Entries whose payload was inflated and re-deflated because the caller could not ship the stored bytes — a delta whose base is outside the request. copied + recompressed == written, always.

Zero for a whole-repository clone, which is why the copy claim survives: a full clone’s selection contains every base, so no entry ever needs rebuilding. It is non-zero exactly at the boundary a narrowed request cuts through, and that is the number worth watching.

deltified: u32

Of the Self::recompressed, how many went out as a computed delta against a base the pack carries rather than as a whole object. deltified <= recompressed, always.

The two rebuilds cost the same receipt and very different bytes, so without this column a boundary-heavy request looks identical whether the re-delta ran or not. Measured on h2h-linear-sha1-2048c-1024f-16k’s narrowed clone: 961 recompressed, of which 859 deltified, and the pack fell from 11 613 666 bytes to 6 424 726 for the identical 31 805 objects.

rebased: u32

Entries whose OFS_DELTA distance had to be re-encoded because the gap to their base changed. Zero only if the subset happened to preserve every gap, which for anything but a whole pack it will not.

bytes: u64

Bytes on the wire, trailer included.
