Enum ProtocolVersion 

pub enum ProtocolVersion {
    V10,
    V20 {
        protocol_num: u8,
        target_sw: u8,
    },
}

Represents the protocol version a device supports.

Variants

V10

The older HID++1.0 protocol. Mostly used for receivers.

V20

All newer protocols starting from HID+2.0.

Traditionally, the version was split into a major and a minor version, defining the concrete protocol version. These two values were later redefined to serve the purpose of indicating which host software to target.

Fields

protocol_num: u8

The protocol number is a field that hints the host software if it should support the device.

protocol_num = 2 : Intended target SW is Logitech SetPoint
protocol_num = 3 : Intended OEM SW described in target_sw field
protocol_num = 4 : Intended target SW described in target_sw field

target_sw: u8

When protocol_num >= 3 this field further hints at which software should support the device. Otherwise the value is zero.

Trait Implementations

impl Clone for ProtocolVersion

fn clone(&self) -> ProtocolVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProtocolVersion

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

Formats the value using the given formatter.

impl Hash for ProtocolVersion

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 ProtocolVersion

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