Struct bevy_render::render_resource::BindGroupLayoutEntryBuilder

pub struct BindGroupLayoutEntryBuilder { /* private fields */ }

Helper for constructing bind group layouts.

Allows constructing the layout’s entries as:

let layout = render_device.create_bind_group_layout(
    "my_bind_group_layout",
    &BindGroupLayoutEntries::with_indices(
        // The layout entries will only be visible in the fragment stage
        ShaderStages::FRAGMENT,
        (
            // Screen texture
            (2, texture_2d(TextureSampleType::Float { filterable: true })),
            // Sampler
            (3, sampler(SamplerBindingType::Filtering)),
        ),
    ),
);

instead of

let layout = render_device.create_bind_group_layout(
    "my_bind_group_layout",
    &[
        // Screen texture
        BindGroupLayoutEntry {
            binding: 2,
            visibility: ShaderStages::FRAGMENT,
            ty: BindingType::Texture {
                sample_type: TextureSampleType::Float { filterable: true },
                view_dimension: TextureViewDimension::D2,
                multisampled: false,
            },
            count: None,
        },
        // Sampler
        BindGroupLayoutEntry {
            binding: 3,
            visibility: ShaderStages::FRAGMENT,
            ty: BindingType::Sampler(SamplerBindingType::Filtering),
            count: None,
        },
    ],
);

render_device.create_bind_group_layout(
    "my_bind_group_layout",
    &BindGroupLayoutEntries::sequential(
        ShaderStages::FRAGMENT,
        (
