Struct Stream

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

A stream of value groups which are meant to be used together (e.g. 3 floats representing a vertex position).

Implementations

impl<'a> Stream<'a>

pub fn from_slice<T>(slice: &'a [T]) -> Self

Creates a stream from a slice.

Example

use meshopt_rs::Stream;

let positions = vec![[1.0, 2.0, 3.0], [2.0, 3.0, 4.0], [5.0, 6.0, 7.0]];
let stream = Stream::from_slice(&positions);

assert_eq!(stream.len(), positions.len());

pub fn from_slice_with_subset<T>(slice: &'a [T], subset: Range<usize>) -> Self

Creates a stream from a slice with the given byte subset.

Arguments

• subset: subset of data to use inside a T

Example

use meshopt_rs::Stream;

#[derive(Clone, Default)]
#[repr(C)]
struct Vertex {
    position: [f32; 3],
    normal: [f32; 3],
    uv: [f32; 2],
}

let normals_offset = std::mem::size_of::<f32>() * 3;
let normals_size = std::mem::size_of::<f32>() * 3;

let vertices = vec![Vertex::default(); 1];
let normal_stream = Stream::from_slice_with_subset(&vertices, normals_offset..normals_offset+normals_size);

assert_eq!(normal_stream.len(), 1);

pub fn from_bytes<T>( slice: &'a [T], stride: usize, subset: Range<usize>, ) -> Self

Creates a stream from raw bytes.

Arguments

• stride: stride between value groups
• subset: subset of data to use inside a value group

pub fn len(&self) -> usize

Returns length of the stream in value groups.
