Struct SpawnLockFileIdentity 

pub struct SpawnLockFileIdentity {
    pub device: u64,
    pub file: u64,
}

Stable identity for an opened lock file on platforms that expose it.

Kept under this name for callers that already match on it; the mechanic is the facade’s, because “is this still the same file” is a question only the host can answer. Stable identity of an open file on this host.

Two paths that resolve to the same bytes on disk report the same identity, which is what lets a caller notice that the file it opened has since been replaced. The two fields are whatever this host uses to say that: a device and inode, a volume serial and file index, or an equivalent pair. Callers compare them; they do not interpret them.

Fields

device: u64

Device, volume, or platform-equivalent file namespace.

file: u64

Inode, file index, or platform-equivalent file number.
