Struct Fingerprint 

pub struct Fingerprint {
    pub size: u64,
    pub mtime_ns: i64,
    pub ctime_ns: i64,
    pub inode: u64,
    pub dev: u64,
}

The fingerprint used to decide whether an entry really changed.

Size and mtime alone are not enough. mtime is user-settable, and some applications roll it back after modifying a file; ctime is kernel-controlled and cannot be set directly. Borg keys on ctime/size/inode and restic requires both mtime and ctime to match, and this engine follows them: an index that keys purely on mtime is trusting a value userspace can forge.

Fields

size: u64

Apparent file size.

mtime_ns: i64

Modification time in nanoseconds since the Unix epoch.

ctime_ns: i64

Inode-change time in nanoseconds since the Unix epoch.

inode: u64

Platform inode or file identity component.

dev: u64

Platform device or volume identity component.
