Struct web_glitz::pipeline::graphics::TransformFeedbackLayoutDescriptorBuilder

pub struct TransformFeedbackLayoutDescriptorBuilder { /* fields omitted */ }

Builds a new TransformFeedbackLayoutDescriptor.

Example

use web_glitz::pipeline::graphics::{TransformFeedbackLayoutAllocationHint, TransformFeedbackLayoutDescriptorBuilder, TransformFeedbackAttributeDescriptor, TransformFeedbackAttributeType};

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

builder.add_bind_slot()
    .add_attribute(TransformFeedbackAttributeDescriptor {
        ident: "position".into(),
        attribute_type: TransformFeedbackAttributeType::FloatVector3,
        size: 1
    })
    .add_attribute(TransformFeedbackAttributeDescriptor {
        ident: "normal".into(),
        attribute_type: TransformFeedbackAttributeType::FloatVector3,
        size: 1
    });

let layout_descriptor = builder.finish();

Methods

impl TransformFeedbackLayoutDescriptorBuilder

pub fn new(
    allocation_hint: Option<TransformFeedbackLayoutAllocationHint>
) -> 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 TransformFeedbackLayoutAllocationHint for details.

pub fn add_buffer_slot(
    &mut self
) -> TransformFeedbackBufferSlotAttributeAttacher

Adds a transform feedback buffer binding slot to the layout.

pub fn finish(self) -> TransformFeedbackLayoutDescriptor

Finishes building and returns the resulting TransformFeedbackLayoutDescriptor.
