Struct WpSinglePixelBufferManagerV1

pub struct WpSinglePixelBufferManagerV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

global factory for single-pixel buffers

The wp_single_pixel_buffer_manager_v1 interface is a factory for single-pixel buffers.

This interface has no events.

Implementations

impl WpSinglePixelBufferManagerV1

pub fn destroy(&self)

destroy the manager

Destroy the wp_single_pixel_buffer_manager_v1 object.

The child objects created via this interface are unaffected.

pub fn create_u32_rgba_buffer<U, D>( &self, r: u32, g: u32, b: u32, a: u32, qh: &QueueHandle<D>, udata: U, ) -> WlBuffer

where U: Send + Sync + 'static, D: Dispatch<WlBuffer, U> + 'static,

create a 1×1 buffer from 32-bit RGBA values

Create a single-pixel buffer from four 32-bit RGBA values.

Unless specified in another protocol extension, the RGBA values use pre-multiplied alpha.

The width and height of the buffer are 1.

The r, g, b and a arguments valid range is from UINT32_MIN (0) to UINT32_MAX (0xffffffff).

These arguments should be interpreted as a percentage, i.e.

• UINT32_MIN = 0% of the given color component
• UINT32_MAX = 100% of the given color component

impl PartialEq<Weak<WpSinglePixelBufferManagerV1>> for WpSinglePixelBufferManagerV1

fn eq(&self, other: &Weak<WpSinglePixelBufferManagerV1>) -> 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.
