Struct ResolvedFile 

pub struct ResolvedFile {
    pub layout: RegionLayout,
    pub total_len: u64,
    pub track_id: i64,
    pub content_version: i64,
    pub backing_path: PathBuf,
    pub stamp: BackingStamp,
    pub mtime_secs: i64,
    pub last_page: Mutex<Option<(u64, u64, Vec<u8>)>>,
    pub cache_bytes: u64,
    pub streams_db_rowid: bool,
}

A fully resolved synthesized file: its segment layout, total size, the content version it was built from, and where the backing audio lives.

Fields

layout: RegionLayout

total_len: u64

track_id: i64

Track id this entry resolves. Lets the stateless read path recheck the live content_version under its WAL snapshot (#502), mirroring the handle fast path’s use of the handle’s track_id.

content_version: i64

backing_path: PathBuf

stamp: BackingStamp

mtime_secs: i64

last_page: Mutex<Option<(u64, u64, Vec<u8>)>>

One-entry memo of the last patched Ogg page, so consecutive reads skip re-patching the page straddling a chunk boundary. Empty for non-Ogg files and reset whenever this resolved entry is rebuilt. (Concrete type spelled out rather than ogg_index::LastPageMemo because that module is private.)

cache_bytes: u64

Approximate resident bytes this entry costs the cache (sum of Inline segment bytes; backing/art/ogg-audio bytes are not resident).

streams_db_rowid: bool

Precomputed from the layout: true if any segment is streamed from the DB by a rowid (BinaryTag/ArtImage/OggArtSlice). Gates the transactional content_version guard in the read fast path so plain Inline/BackingAudio layouts pay no per-read cost (#502).

Trait Implementations
