Enum Classification 

pub enum Classification {
    Unchanged,
    MtimeOnly {
        hash: String,
    },
    Modified {
        hash: Option<String>,
    },
    Added,
}

Per-file change classification against a Manifest.

Distinguishes the four cases that incremental update cares about: no content read (Unchanged), mtime drift but bytes still match (MtimeOnly), bytes actually changed (Modified), or new since last save (Added). Files removed since last save live in DiskState::removed, not here.

Variants

Unchanged

(size, mtime) matched the manifest exactly — no content read.

MtimeOnly

mtime drifted but the BLAKE3 content hash still matches. Carries the hash we computed so callers don’t re-read the file.

Fields

hash: String

Modified

File was in the manifest but bytes have actually changed. hash is Some when we computed one during classification (only happens when size matched and the manifest had a hash), otherwise None.

Fields

hash: Option<String>

Added

File is new — not in the manifest.
