Trait DataType 

pub trait DataType {
    const ATTR_FORMAT: ATTRType;
    const BYTE_COUNT: usize;
    const ELEM_COUNT: usize;

    // Required method
    fn u8ify(&self) -> Vec<u8> ;
}

Trait for types that can be used as vertex or instance attribute data.

Implemented for i8, u8, i16, u16, i32, u32, f32, f64 and their fixed-size arrays [T; 2], [T; 3], [T; 4].

Constants

• DataType::ATTR_FORMAT — the GL attribute type enum
• DataType::BYTE_COUNT — size of one scalar element in bytes
• DataType::ELEM_COUNT — number of scalar elements (1 for scalars, N for arrays)

Example

use optic_render::asset::attr::DataType;

assert_eq!(<f32 as DataType>::BYTE_COUNT, 4);
assert_eq!(<[f32; 3] as DataType>::ELEM_COUNT, 3);

Required Associated Constants

const ATTR_FORMAT: ATTRType

const BYTE_COUNT: usize

const ELEM_COUNT: usize

Required Methods

fn u8ify(&self) -> Vec<u8>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
