Enum PositionLayout 

#[repr(u8)]
pub enum PositionLayout {
    Packed3 = 1,
    Padded4 = 2,
}

How to interleave atom positions for upload.

Variants

Packed3 = 1

Tightly packed [x, y, z], 12-byte stride. Suits vertex buffers (Float32x3).

Padded4 = 2

[x, y, z, 1.0], 16-byte stride. Required for storage/uniform buffers, where WGSL array<vec3<f32>> and std140/std430 vec3 arrays use a 16-byte stride; uploading Packed3 there silently misreads every atom after the first.
