Trait VertexLoad

pub trait VertexLoad<'a, C: ?Sized = ()>: Clone {
    // Required methods
    fn position(ctx: &C, reader: &SourceReader<'a, XYZ>, index: u32) -> Self;
    fn add_normal(
        &mut self,
        ctx: &C,
        reader: &SourceReader<'a, XYZ>,
        index: u32,
    );
    fn add_texcoord(
        &mut self,
        ctx: &C,
        reader: &SourceReader<'a, ST>,
        index: u32,
        set: Option<u32>,
    );
}

A trait, to be implemented by user types, to describe how to construct a vertex object from the stored data. The context C is an arbitrary type that can be used for getting (or modifying, with interior mutability) additional data to create the object.

Required Methods

fn position(ctx: &C, reader: &SourceReader<'a, XYZ>, index: u32) -> Self

Construct a new vertex using only position data.

The position index is provided as is, but the intended use is to call reader.get(i) and use the resulting [f32; 3] as the position.

fn add_normal(&mut self, ctx: &C, reader: &SourceReader<'a, XYZ>, index: u32)

Add normal data to a vertex.

The position index is provided as is, but the intended use is to call reader.get(i) and use the resulting [f32; 3] as the normal.

fn add_texcoord( &mut self, ctx: &C, reader: &SourceReader<'a, ST>, index: u32, set: Option<u32>, )

Add texture coordinate data to a vertex.

The position index is provided as is, but the intended use is to call reader.get(i) and use the resulting [f32; 2] as the u-v data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
