Enum Backend 

pub enum Backend {
    Auto,
    Usb,
    Wpd,
}

Selects which backend MtpDeviceBuilder opens.

Auto (the default) picks per platform: on Windows it prefers the WPD backend (phones are bound to the WPD driver, not WinUSB), falling back to PTP-over-USB only if no WPD device is present; on other platforms it uses USB. Usb forces PTP-over-USB (e.g. a Zadig/WinUSB-bound camera on Windows); Wpd forces Windows WPD-over-COM (and errors as unsupported off Windows).

Variants

Auto

Platform default: Windows → WPD then USB; elsewhere → USB.

Usb

Force PTP-over-USB.

Wpd

Force Windows WPD-over-COM.

Trait Implementations

impl Clone for Backend

fn clone(&self) -> Backend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Backend

impl Debug for Backend

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

Formats the value using the given formatter.

impl Default for Backend

fn default() -> Backend

Returns the “default value” for a type.

impl Eq for Backend

impl PartialEq for Backend

fn eq(&self, other: &Backend) -> 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.
