Struct evdev_rs::UninitDevice

pub struct UninitDevice { /* fields omitted */ }

Opaque struct representing an evdev device with no backing file

Implementations

impl UninitDevice

pub fn new() -> Option<UninitDevice>

Initialize a new libevdev device.

Generally you should use Device::new_from_file instead of this method This function only initializes the struct to sane default values. To actually hook up the device to a kernel device, use set_file.

pub fn set_file(self, file: File) -> Result<Device>

Set the file for this struct and initialize internal data.

If the device changed and you need to re-read a device, use Device::new_from_file method. If you need to change the file after closing and re-opening the same device, use change_file.

pub fn set_fd(self, file: File) -> Result<Device>

👎 Deprecated since 0.5.0:

Prefer set_file. Some function names were changed so they more closely match their type signature. See issue 42 for discussion https://github.com/ndesh26/evdev-rs/issues/42

Trait Implementations

impl DeviceWrapper for UninitDevice

fn raw(&self) -> *mut libevdev

fn enable(&self, blob: &dyn Any) -> Result<()>

Forcibly enable an EventType/InputProp on this device, even if the underlying device does not support it. While this cannot make the device actually report such events, it will now return true for has().

fn enable_property(&self, prop: &InputProp) -> Result<()>

Enables this property, a call to set_file will overwrite any previously set values

fn enable_event_type(&self, ev_type: &EventType) -> Result<()>

Forcibly enable an event type on this device, even if the underlying device does not support it. While this cannot make the device actually report such events, it will now return true for libevdev_has_event_type().

fn enable_event_code(
    &self,
    ev_code: &EventCode,
    blob: Option<&dyn Any>
) -> Result<()>

Forcibly enable an event type on this device, even if the underlying device does not support it. While this cannot make the device actually report such events, it will now return true for libevdev_has_event_code().

fn disable(&self, blob: &dyn Any) -> Result<()>

Forcibly disable an EventType/EventCode on this device, even if the underlying device provides it. This effectively mutes the respective set of events. has() will return false for this EventType/EventCode

fn disable_event_type(&self, ev_type: &EventType) -> Result<()>

Forcibly disable an event type on this device, even if the underlying device provides it. This effectively mutes the respective set of events. libevdev will filter any events matching this type and none will reach the caller. libevdev_has_event_type() will return false for this type.

fn disable_event_code(&self, code: &EventCode) -> Result<()>

Forcibly disable an event code on this device, even if the underlying device provides it. This effectively mutes the respective set of events. libevdev will filter any events matching this type and code and none will reach the caller. has_event_code will return false for this code.

fn has(&self, blob: &dyn Any) -> bool

Returns true if device support the InputProp/EventType/EventCode and false otherwise

fn has_property(&self, prop: &InputProp) -> bool

Returns true if device support the property and false otherwise

fn has_event_type(&self, ev_type: &EventType) -> bool

Returns true is the device support this event type and false otherwise

fn has_event_code(&self, code: &EventCode) -> bool

Return true is the device support this event type and code and false otherwise

fn name(&self) -> Option<&str>

Get device’s name, as set by the kernel, or overridden by a call to set_name

fn phys(&self) -> Option<&str>

Get device’s physical location, as set by the kernel, or overridden by a call to set_phys

fn uniq(&self) -> Option<&str>

Get device’s unique identifier, as set by the kernel, or overridden by a call to set_uniq

fn set_name(&self, field: &str)

fn set_phys(&self, field: &str)

fn set_uniq(&self, field: &str)

fn product_id(&self) -> u16

fn vendor_id(&self) -> u16

fn set_bustype(&self, field: u16)

fn set_version(&self, field: u16)

fn abs_info(&self, code: &EventCode) -> Option<AbsInfo>

Get the axis info for the given axis, as advertised by the kernel.

fn set_abs_info(&self, code: &EventCode, absinfo: &AbsInfo)

Change the abs info for the given EV_ABS event code, if the code exists.

fn event_value(&self, code: &EventCode) -> Option<i32>

Returns the current value of the event type.

fn set_event_value(&self, code: &EventCode, val: i32) -> Result<()>

Set the value for a given event type and code.

fn abs_minimum(&self, code: u32) -> Result<i32>

fn abs_maximum(&self, code: u32) -> Result<i32>

fn abs_fuzz(&self, code: u32) -> Result<i32>
