Struct evdev::InputEvent
source · pub struct InputEvent(/* private fields */);
Expand description
A wrapped input_event
returned by the input device via the kernel.
input_event
is a struct containing four fields:
time: timeval
type_: u16
code: u16
value: s32
The meaning of the “code” and “value” fields will depend on the underlying type of event.
Implementations§
source§impl InputEvent
impl InputEvent
sourcepub fn timestamp(&self) -> SystemTime
pub fn timestamp(&self) -> SystemTime
Returns the timestamp associated with the event.
sourcepub fn event_type(&self) -> EventType
pub fn event_type(&self) -> EventType
Returns the type of event this describes, e.g. Key, Switch, etc.
sourcepub fn kind(&self) -> InputEventKind
pub fn kind(&self) -> InputEventKind
A convenience function to return self.code()
wrapped in a certain newtype determined by
the type of this event.
This is useful if you want to match events by specific key codes or axes. Note that this does not capture the event value, just the type and code.
sourcepub fn value(&self) -> i32
pub fn value(&self) -> i32
Returns the raw “value” field directly from input_event.
For keys and switches the values 0 and 1 map to pressed and not pressed respectively. For axes, the values depend on the hardware and driver implementation.
sourcepub fn new(type_: EventType, code: u16, value: i32) -> Self
pub fn new(type_: EventType, code: u16, value: i32) -> Self
Create a new InputEvent. Only really useful for emitting events on virtual devices.
sourcepub fn new_now(type_: EventType, code: u16, value: i32) -> Self
pub fn new_now(type_: EventType, code: u16, value: i32) -> Self
Create a new InputEvent with the time field set to “now” on the system clock.
Note that this isn’t usually necessary simply for emitting events on a virtual device, as
even though InputEvent::new
creates an input_event
with the time field as zero,
the kernel will update input_event.time
when it emits the events to any programs reading
the event “file”.
