Struct web_glitz::pipeline::graphics::VertexInputLayoutDescriptorBuilder

pub struct VertexInputLayoutDescriptorBuilder { /* fields omitted */ }

Builds a new VertexInputLayoutDescriptor.

Example

use web_glitz::pipeline::graphics::{AttibuteLayoutAllocationHint, VertexInputLayoutDescriptorBuilder, VertexInputLayoutAllocationHint, InputRate, VertexAttributeDescriptor};
use web_glitz::pipeline::graphics::attribute_format::VertexAttributeFormat;

let mut builder = VertexInputLayoutDescriptorBuilder::new(Some(VertexInputLayoutAllocationHint {
    bind_slot_count: 2,
    attribute_count: 3
}));

builder.add_buffer_slot(28, InputRate::PerVertex)
    .add_attribute(VertexAttributeDescriptor {
        location: 0,
        offset_in_bytes: 0,
        format: VertexAttributeFormat::Float4_f32
    })
    .add_attribute(VertexAttributeDescriptor {
        location: 1,
        offset_in_bytes: 16,
        format: VertexAttributeFormat::Float3_f32
    });

builder.add_buffer_slot(16, InputRate::PerInstance)
    .add_attribute(VertexAttributeDescriptor {
        location: 2,
        offset_in_bytes: 0,
        format: VertexAttributeFormat::Float4_f32
    });

let layout_descriptor = builder.finish();

Methods

impl VertexInputLayoutDescriptorBuilder

pub fn new(allocation_hint: Option<VertexInputLayoutAllocationHint>) -> Self

Creates a new builder.

Takes an optional allocation_hint to help reduce the number of allocations without over- allocating. With an accurate allocation hint the builder will only allocate once. See VertexInputLayoutAllocationHint for details.

pub fn add_buffer_slot(
    &mut self,
    stride: u8,
    input_rate: InputRate
) -> VertexBufferSlotAttributeAttacher

Adds a vertex buffer binding slot to the layout.

pub fn finish(self) -> VertexInputLayoutDescriptor

Finishes building and returns the resulting VertexInputLayoutDescriptor.
