Struct AndroidEvent 

pub struct AndroidEvent {
    pub type: i32,
    pub code: i32,
    pub value: i32,
    pub display: i32,
}

The android input event system is a framework for handling input from a variety of devices by generating events that describe changes in the state of the devices and forwarding them to user space applications.

An AndroidEvents will be delivered directly to the kernel as is.

Fields

type: i32

The type of the event. The types of the event are specified by the android kernel. Some examples are: EV_SYN, EV_KEY, EV_SW, etc.. The exact definitions can be found in the input.h header file.

code: i32

The actual code to be send to the kernel. The actual meaning of the code depends on the type definition.

value: i32

The actual value of the event.

display: i32

The display id associated with this input event.

Trait Implementations

impl Clone for AndroidEvent

fn clone(&self) -> AndroidEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AndroidEvent

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

Formats the value using the given formatter.

impl Default for AndroidEvent

fn default() -> Self

Returns the “default value” for a type.

impl Hash for AndroidEvent

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 Message for AndroidEvent

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where 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( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for AndroidEvent

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