Struct ObjectHandle 

pub struct ObjectHandle(pub u64);

Opaque handle for an object on a device.

The inner value is a backend-defined token, meaningful only within a single open device session — not a stable, cross-session, or wire-level identifier. The USB/PTP backend uses the raw PTP object handle; the WPD backend maps the token to an opaque WPD object-ID string. Treat it as opaque: pass it back to the same open device, don’t persist it across sessions, and don’t derive meaning from its numeric value. (Some devices, notably Android, re-key handles even within a session — see crate::Error::StaleHandle.)

Implementations

impl ObjectHandle

pub const ROOT: Self

The storage root (an object’s parent is ROOT when it sits at the top of a storage).

pub const ALL: Self

Sentinel meaning “all objects” for recursive listing.

Trait Implementations

impl Clone for ObjectHandle

fn clone(&self) -> ObjectHandle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ObjectHandle

impl Debug for ObjectHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ObjectHandle

fn default() -> ObjectHandle

Returns the “default value” for a type.

impl Eq for ObjectHandle

impl From<ObjectHandle> for ObjectHandle

fn from(h: PtpObjectHandle) -> Self

Converts to this type from the input type.

impl Hash for ObjectHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ObjectHandle

fn eq(&self, other: &ObjectHandle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
