Enum FileId 

#[non_exhaustive]
pub enum FileId {
    NtfsRef {
        entry: u64,
        seq: u16,
    },
    ExtInode {
        ino: u64,
        gen: u32,
    },
    ApfsOid {
        oid: u64,
        xid: u64,
    },
    FatDirEntry {
        cluster: u32,
        index: u16,
    },
    IsoExtent {
        block: u32,
    },
    Opaque(u64),
}

Filesystem-specific stable identity. The address domain matches each FS’s real identity primitive, so a reused slot is never confused with the original.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NtfsRef

NTFS MFT reference: record number + sequence.

Fields

entry: u64

seq: u16

ExtInode

ext2/3/4 inode + generation.

Fields

ino: u64

gen: u32

ApfsOid

APFS object id + transaction id.

Fields

oid: u64

xid: u64

FatDirEntry

FAT/exFAT physical directory-entry address (no stable inode).

Fields

cluster: u32

index: u16

IsoExtent

ISO 9660 path-table / extent address.

Fields

block: u32

Opaque(u64)

A filesystem with a plain inode and nothing finer.
