Struct EvdevDevice 

pub struct EvdevDevice {
    pub device_id: Option<u32>,
    pub device_num: Option<u32>,
    pub name: Option<String>,
    pub phys: Option<String>,
    pub uniq: Option<String>,
    pub id: Option<Identifier>,
    pub absolute_axis_infos: HashMap<u32, AbsInfo>,
    pub ev_bitmask: Option<Vec<u8>>,
    pub event_type_bitmasks: HashMap<u32, Vec<u8>>,
    pub prop_bitmask: Option<Vec<u8>>,
    pub axis_states: HashMap<u32, AxisMap>,
    pub abs_mt_states: HashMap<u32, SlotValuesMap>,
}

The properties of an input device that don’t change during the time that it’s connected, as well as the current values for all of its axes.

Next ID: 13

Fields

device_id: Option<u32>

The device’s unique ID number. This need not be the number of its /dev/input/event node.

device_num: Option<u32>

The number of the evdev device (i.e. from its /dev/input/eventX node path).

name: Option<String>

The device’s name.

phys: Option<String>

The physical path to the device in the system hierarchy.

uniq: Option<String>

The unique identification code for the device (if it has one).

id: Option<Identifier>

The device’s ID numbers.

absolute_axis_infos: HashMap<u32, AbsInfo>

A map of information for each of the device’s absolute axes. Keys are the Linux ABS_* constants.

ev_bitmask: Option<Vec<u8>>

Bitmask specifying which types of events the device declares.

event_type_bitmasks: HashMap<u32, Vec<u8>>

A map of bitmasks specifying which axes of each type the device declares. Keys are the Linux EV_* constants.

prop_bitmask: Option<Vec<u8>>

Bitmask of properties declared by the device.

axis_states: HashMap<u32, AxisMap>

Current states of device axes.

The keys are the Linux event type constants (e.g. EV_KEY, EV_ABS, etc.). We don’t need to keep track of states for all axis types, only KEY, SW, LED, and ABS, so only those will have entries in this map. States for ABS_MT_* axes (which have multiple slots) will be kept in abs_mt_states instead.

abs_mt_states: HashMap<u32, SlotValuesMap>

Current states of ABS_MT_* axes other than ABS_MT_SLOT. The keys are the ABS axis codes.

Trait Implementations

impl Clone for EvdevDevice

fn clone(&self) -> EvdevDevice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvdevDevice

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

Formats the value using the given formatter.

impl Default for EvdevDevice

fn default() -> Self

Returns the “default value” for a type.

impl Message for EvdevDevice

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

impl PartialEq for EvdevDevice

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