custom_shader(
    CustomShader::new(
        "fn quickgui_fragment(input: QuickGuiShaderInput) -> vec4<f32> { return vec4<f32>(input.uv.x, 0.3, input.uv.y, 1.0); }",
    )
    .expect("shader"),
)
.size(260.0, 150.0)

#导入

从 quickgui 导入 CustomShader。

use quickgui::*;

#用法

custom_shader(
    CustomShader::new(
        "fn quickgui_fragment(input: QuickGuiShaderInput) -> vec4<f32> { return vec4<f32>(input.uv.x, 0.3, input.uv.y, 1.0); }",
    )
    .expect("shader"),
)

pub fn custom_shader(shader: impl Into<CustomShader>) -> Element

Create a retained rectangle painted by validated application WGSL. Like the web canvas default, its initial size is 300 by 150 logical pixels. The shader remains still until application state invalidates the view or explicitly requests another frame.
