Struct VertexBuffer

pub struct VertexBuffer {
    pub id: u32,
}

A abstract representation of a vertex buffer

Example

   let vertices = vec![
       0.5, 0.5, 0.0, // top right
       0.5, -0.5, 0.0, // bottom right
       -0.5, -0.5, 0.0, // bottom left
       -0.5, 0.5, 0.0, // top left
   ];

   // static
   let vbo1 = VertexBuffer::new(calc_bytes_size(&vertices) as isize, Some(&vertices));

   // Dynamic
   let vbo2 = VertexBuffer::new(calc_bytes_size(&vertices) as isize);

   // send half of the vertices
   vbo2.send_data(48 / 2, 0, vertices);

Fields

id: u32

Implementations

impl VertexBuffer

pub fn new<T>(size: isize, vertices: Option<&Vec<T>>) -> Self

Return a VertexBuffer with the allocated size provided, the buffer data is static only if the verticies isn’t None, else, the buffer data is dynamic

Arguments

• size - The size in bytes of the data to allocate
• vertices - A optional data to write

pub fn send_data<T>(&self, size: isize, offset: isize, vertices: &Vec<T>)

Write data that wasn’t provided on the new function

Arguments

• size - The size in bytes of the data to write
• offset - Point to a offset in the allocated space
• vertices - Data to write

pub fn bind(&self)

pub fn unbind(&self)

Trait Implementations

impl Drop for VertexBuffer

fn drop(&mut self)

Executes the destructor for this type.
