Struct ObjectHandle 

pub struct ObjectHandle(pub u32);

32-bit object handle assigned by the device.

Tuple Fields

0: u32

Implementations

impl ObjectHandle

pub const ROOT: Self

Root folder (parent = root means object is in storage root).

pub const ALL: Self

All objects (used in GetObjectHandles to list recursively).

pub const SEND_ROOT: Self

Storage root as the destination of a new object: SendObjectInfo parameter 2.

MTP 1.1 D.2.12 is explicit: “If the initiator wishes to place an object in the root of a given storage, it shall indicate the desired storage in the first parameter and include a value of 0xFFFFFFFF in the second parameter.” A 0 there means “no parent specified, responder may choose”, so responders look it up as a handle and reject it: Android’s MtpServer only maps MTP_PARENT_ROOT (0xFFFFFFFF) to the storage path, and libhaze (Nintendo Switch homebrew, #21) only maps 0xFFFFFFFF to its storage object. Both answer 0 with InvalidObjectHandle.

The spec is asymmetric, so don’t unify this with ObjectHandle::ROOT: MoveObject/CopyObject (D.2.25/D.2.26) spell the same destination 0x00000000.
