Struct IndexBuffer

pub struct IndexBuffer {
    pub id: u32,
}

A abstract representation of a index buffer

Example

   let indices = vec![
       0, 1, 3, // first Triangle
       1, 2, 3, // second Triangle
   ];

   // static
   let ibo1 = VertexBuffer::new(calc_bytes_size(&indices) as isize, Some(&vertices));

   // Dynamic
   let ibo2 = VertexBuffer::new(calc_bytes_size(&indices) as isize);

   // send half of the vertices
   ibo2.send_data(24 / 2, 0, &indices);

Fields

id: u32

Implementations

impl IndexBuffer

pub fn new(size: isize, indices: Option<&Vec<i32>>) -> Self

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

Arguments

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

pub fn send_data(&self, size: isize, offset: isize, indices: &Vec<i32>)

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
• indices - Data to write

pub fn bind(&self)

pub fn unbind(&self)

Trait Implementations

impl Drop for IndexBuffer

fn drop(&mut self)

Executes the destructor for this type.
