Struct ggez::graphics::ShaderParams

pub struct ShaderParams<Uniforms: AsStd140> { /* private fields */ }

Parameters that can be passed to a custom shader, including uniforms, images, and samplers.

Create with ShaderParamsBuilder.

These parameters are bound to group 3. With WGSL, for example,

ggez::graphics::ShaderParamsBuilder::new(&my_uniforms)
    .images(&[&image1, &image2], &[sampler1], false)
    .build(&mut ctx.gfx)

Corresponds to…

@group(3) @binding(0)
var<uniform> my_uniforms: MyUniforms;
@group(3) @binding(1)
var image1: texture_2d<f32>;
@group(3) @binding(2)
var image2: texture_2d<f32>;
@group(3) @binding(3)
var sampler1: sampler;

Implementations

impl<Uniforms: AsStd140> ShaderParams<Uniforms>

pub fn set_uniforms(&mut self, ctx: &mut Context, uniforms: &Uniforms)

Updates the uniform data.

When called, [Canvas::set_shader_params] (or [Canvas::set_text_shader_params]) needs to be called again for the new uniforms to take effect.

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

Formats the value using the given formatter.
