Struct FileIdentity 

pub struct FileIdentity { /* private fields */ }

A filesystem object’s identity: the record’s 128-bit file ID, optionally qualified by the volume it lives on.

A file ID is unique only within a volume, so the same ID may name different objects on different volumes. An unqualified identity is therefore not globally meaningful and must not be compared across volumes; is_volume_qualified reports which kind this is.

The 16 identifier bytes are kept exactly as the record reported them. They are deliberately not folded into a u128, which would impose an endianness the native value does not have.

Implementations

impl FileIdentity

pub const fn new(id: [u8; 16], volume_serial: Option<u64>) -> Self

Build an identity from a record’s identifier bytes and, when it was obtained, the volume serial that qualifies them.

pub const fn id_bytes(&self) -> [u8; 16]

The record’s 16 identifier bytes, verbatim.

pub const fn volume_serial(&self) -> Option<u64>

The volume serial, when the request obtained one.

pub const fn is_volume_qualified(&self) -> bool

Whether this identity is globally meaningful.
