Struct nannou_wgpu::BindGroupLayoutBuilder

pub struct BindGroupLayoutBuilder { /* fields omitted */ }

A type aimed at simplifying the creation of a bind group layout.

Implementations

impl LayoutBuilder

pub fn new() -> Self

Begin building the bind group layout.

pub fn binding(self, visibility: ShaderStages, ty: BindingType) -> Self

Specify a new binding.

The binding position of each binding will be inferred as the index within the order that they are added to this builder type. If you require manually specifying the binding location, you may be better off not using the BindGroupLayoutBuilder and instead constructing the BindGroupLayout and BindGroup manually.

pub fn uniform_buffer(
    self,
    visibility: ShaderStages,
    has_dynamic_offset: bool
) -> Self

Add a uniform buffer binding to the layout.

pub fn storage_buffer(
    self,
    visibility: ShaderStages,
    has_dynamic_offset: bool,
    read_only: bool
) -> Self

Add a storage buffer binding to the layout.

pub fn sampler(self, visibility: ShaderStages, filtering: bool) -> Self

Add a sampler binding to the layout.

pub fn comparison_sampler(
    self,
    visibility: ShaderStages,
    filtering: bool
) -> Self

Add a sampler binding to the layout.

pub fn texture(
    self,
    visibility: ShaderStages,
    multisampled: bool,
    view_dimension: TextureViewDimension,
    sample_type: TextureSampleType
) -> Self

Add a texture binding to the layout.

pub fn texture_from(self, visibility: ShaderStages, texture: &Texture) -> Self

Short-hand for adding a texture binding for a full view of the given texture to the layout.

The multisampled and dimension parameters are retrieved from the Texture itself.

Note that if you wish to take a Cube or CubeArray view of the given texture, you will need to manually specify the TextureViewDimension via the sampled_texture method instead.

pub fn storage_texture(
    self,
    visibility: ShaderStages,
    format: TextureFormat,
    view_dimension: TextureViewDimension,
    access: StorageTextureAccess
) -> Self

Add a storage texture binding to the layout.

pub fn storage_texture_from(
    self,
    visibility: ShaderStages,
    texture: &Texture,
    access: StorageTextureAccess
) -> Self

Short-hand for adding a storage texture binding for a full view of the given texture to the layout.

The format, dimension and sample_type are inferred from the given texture.

pub fn build(self, device: &Device) -> BindGroupLayout

Build the bind group layout from the specified parameters.

Trait Implementations

impl Debug for LayoutBuilder

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

Formats the value using the given formatter.

impl Default for LayoutBuilder

fn default() -> LayoutBuilder

Returns the “default value” for a type.
