Struct InputEvent

pub struct InputEvent {
    pub kernel_timestamp: Option<u64>,
    pub type: Option<u32>,
    pub code: Option<u32>,
    pub value: Option<i32>,
}

Proto version of Linux’s struct input_event. The meaning of types and codes are described in the Linux kernel documentation at https://www.kernel.org/doc/html/latest/input/event-codes.html.

Next ID: 5

Fields

kernel_timestamp: Option<u64>

The monotonic timestamp at which the event occurred, as reported by the kernel, in integer nanoseconds. If omitted, assume that it hasn’t changed since the previous event.

type: Option<u32>

The code grouping for this event, used to distinguish signals, absolute and relative axis changes, and other types of event.

code: Option<u32>

The precise type of the event, such as the axis code for absolute and relative events.

value: Option<i32>

The new value of the axis described by type and code.

Implementations

impl InputEvent

pub fn kernel_timestamp(&self) -> u64

Returns the value of kernel_timestamp, or the default value if kernel_timestamp is unset.

pub fn type(&self) -> u32

Returns the value of type, or the default value if type is unset.

pub fn code(&self) -> u32

Returns the value of code, or the default value if code is unset.

pub fn value(&self) -> i32

Returns the value of value, or the default value if value is unset.

Trait Implementations

impl Clone for InputEvent

fn clone(&self) -> InputEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputEvent

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

Formats the value using the given formatter.

impl Default for InputEvent

fn default() -> Self

Returns the “default value” for a type.

impl Message for InputEvent

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 to a newly allocated buffer.

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

where B: BufMut, 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,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for InputEvent

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