Struct runa_wayland_protocols::wayland::wl_pointer::v9::events::AxisValue120

pub struct AxisValue120 {
    pub axis: Axis,
    pub value120: i32,
}

axis high-resolution scroll event

Discrete high-resolution scroll information.

This event carries high-resolution wheel scroll information, with each multiple of 120 representing one logical scroll step (a wheel detent). For example, an axis_value120 of 30 is one quarter of a logical scroll step in the positive direction, a value120 of -240 are two logical scroll steps in the negative direction within the same hardware event. Clients that rely on discrete scrolling should accumulate the value120 to multiples of 120 before processing the event.

The value120 must not be zero.

This event replaces the wl_pointer.axis_discrete event in clients supporting wl_pointer version 8 or later.

Where a wl_pointer.axis_source event occurs in the same wl_pointer.frame, the axis source applies to this event.

The order of wl_pointer.axis_value120 and wl_pointer.axis_source is not guaranteed.

Fields

axis: Axis

value120: i32

Implementations

impl AxisValue120

pub const OPCODE: u16 = 9u16

Trait Implementations

impl Clone for AxisValue120

fn clone(&self) -> AxisValue120

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AxisValue120

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for AxisValue120

fn deserialize(data: &'a [u8], fds: &'a [RawFd]) -> Result<Self, Error>

Deserialize from the given buffer. Returns deserialized message, and number of bytes and file descriptors consumed, respectively.

impl PartialEq<AxisValue120> for AxisValue120

fn eq(&self, other: &AxisValue120) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AxisValue120

fn serialize<Fds: Extend<OwnedFd>>(self, buf: &mut BytesMut, fds: &mut Fds)

Serialize into the buffered writer. This function returns no errors, failures in seializing are generally program errors, and triggers panicking.

fn len(&self) -> u16

How many bytes will this message serialize to. Including the 8 byte header.

fn nfds(&self) -> u8

How many file descriptors will this message serialize to.
