Struct BindGroupBuilder 

pub struct BindGroupBuilder<'a> { /* private fields */ }

Builds a wgpu::BindGroup against layout one binding at a time.

The plain methods (buffer, texture, sampler, dynamic_buffer) assign @binding(N) in call order, starting at 0 — the common case, matching a layout whose entries are numbered the same way. If your target’s bindings aren’t contiguous from 0 (e.g. looked up by name against a BindGroupTarget, as GPUBindingInstance does), use the _at variants to assign an explicit @binding(N) instead.

let bind_group = BindGroupBuilder::new(&layout)
    .label("camera_bind_group")
    .buffer(&camera_buffer)
    .build(&device);

Implementations

impl<'a> BindGroupBuilder<'a>

pub fn new(layout: &'a BindGroupLayout) -> Self

pub fn label(self, label: impl Into<Option<&'a str>>) -> Self

pub fn buffer(self, buffer: &'a Buffer) -> Self

Binds buffer in its entirety at the next @binding(N) (call order, starting at 0).

pub fn buffer_at(self, binding: u32, buffer: &'a Buffer) -> Self

Same as buffer but at an explicit @binding(N).

pub fn dynamic_buffer(self, buffer: &'a Buffer, element_size: u64) -> Self

Binds buffer scoped to one element_size-sized element — not the whole buffer, since the dynamic offset passed to set_bind_group at draw/dispatch time is added on top of this base range, and wgpu validates offset + size <= buffer size — at the next @binding(N), for a buffer built by DynamicBufferBuilder.

pub fn dynamic_buffer_at( self, binding: u32, buffer: &'a Buffer, element_size: u64, ) -> Self

Same as dynamic_buffer but at an explicit @binding(N).

pub fn texture(self, view: &'a TextureView) -> Self

Binds view at the next @binding(N).

pub fn texture_at(self, binding: u32, view: &'a TextureView) -> Self

Same as texture but at an explicit @binding(N).

pub fn sampler(self, sampler: &'a Sampler) -> Self

Binds sampler at the next @binding(N).

pub fn sampler_at(self, binding: u32, sampler: &'a Sampler) -> Self

Same as sampler but at an explicit @binding(N).

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