Struct VolumeStatFetcher 

pub struct VolumeStatFetcher {
    handle: OwnedHandle,
    failures: AtomicU64,
}

Live stat fetcher: opens the file by FRN on the same volume and reads size + mtime. Read-only, never follows the open with any mutation.

Fields

handle: OwnedHandle

failures: AtomicU64

Implementations

impl VolumeStatFetcher

pub fn open(drive: &str) -> Result<Self, UsnError>

Open a read-only volume handle for per-file stat lookups by FRN.

Errors

Returns UsnError::OpenVolume if the volume handle cannot be opened.

impl VolumeStatFetcher

fn note_failure(&self, frn: u64, stage: &str)

Failures here are expected (file deleted before we look) but a flood of them is not — count every one, log the first few with the win32 code so the pattern is diagnosable.

Trait Implementations

impl StatFetcher for VolumeStatFetcher

fn stat(&self, frn: u64) -> Option<(u64, i64)>

Look up the current size (bytes) and mtime for an FRN, or None when the file is already gone or the fetcher has no answer.
