Struct ExeFingerprint 

pub struct ExeFingerprint {
    pub path: PathBuf,
    pub mtime_nanos: i64,
    pub size: u64,
}

A running-or-on-disk executable’s identity, for drift comparison. The path is canonicalized (so symlink vs target, ~/.cargo/bin vs target/debug, are compared apples-to-apples); mtime_nanos/size are compared only for equality against a fingerprint of the SAME logical binary, so coarse clocks only ever cost an advisory false verdict, never a crash.

Fields

path: PathBuf

Canonicalized absolute path of the executable.

mtime_nanos: i64

File mtime as nanoseconds since the Unix epoch (i64 holds ~year 2262).

size: u64

File size in bytes.

Implementations

impl ExeFingerprint

pub fn of(path: &Path) -> Option<ExeFingerprint>

Stat path (canonicalizing it) into a fingerprint. Returns None on any error – a missing file, a stat failure, or an mtime that does not fit an i64 of nanoseconds. The caller treats None as Unknown (silent, never a false alarm); a drift check must never crash a status/list.

pub fn current() -> Option<ExeFingerprint>

Fingerprint the current process’s own executable. The daemon calls this once at startup to record what it is running; None if current_exe() or the stat fails (the daemon then reports no fingerprint, and every client check fails safe to Unknown).
