Struct PoolKey

pub struct PoolKey {
    pub width: u32,
    pub height: u32,
    pub needs_stencil: bool,
    pub ping: bool,
}

Exact allocation class for a reusable offscreen slot.

Examples

use ailloli_ui_render_wgpu::offscreen_pool::PoolKey;
let key = PoolKey::color(0, 20, true);
assert_eq!((key.width, key.height, key.needs_stencil, key.ping), (1, 20, true, false));

Fields

width: u32

Allocation width in physical pixels; constructors clamp it to at least one.

height: u32

Allocation height in physical pixels; constructors clamp it to at least one.

needs_stencil: bool

Whether the slot owns a depth/stencil attachment.

ping: bool

false = primary offscreen color ; true = ping-pong buffer for blur.

Implementations

impl PoolKey

pub fn color(width: u32, height: u32, needs_stencil: bool) -> Self

Creates a primary color-slot key with optional stencil.

Examples

use ailloli_ui_render_wgpu::offscreen_pool::PoolKey;
let key = PoolKey::color(64, 32, false);
assert_eq!((key.width, key.height, key.ping), (64, 32, false));

pub fn ping_pong(width: u32, height: u32) -> Self

Creates a color-only ping-pong key for effects.

Examples

use ailloli_ui_render_wgpu::offscreen_pool::PoolKey;
let key = PoolKey::ping_pong(8, 0);
assert_eq!((key.height, key.needs_stencil, key.ping), (1, false, true));

Trait Implementations

impl Clone for PoolKey

fn clone(&self) -> PoolKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PoolKey

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

Formats the value using the given formatter.

impl Hash for PoolKey

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 PartialEq for PoolKey

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