Struct coffee::graphics::Batch

pub struct Batch { /* fields omitted */ }

A collection of quads that will be drawn all at once using the same Image.

Methods

impl Batch

pub fn new(image: Image) -> Self

Creates a new Batch using the given Image.

pub fn add<Q: IntoQuad>(&mut self, quad: Q)

Adds a quad to the Batch.

pub fn draw(&self, target: &mut Target)

Draws the Batch on the given Target.

pub fn clear(&mut self)

Clears the Batch contents.

This is useful to avoid creating a new batch every frame and reallocating the same memory.

Trait Implementations

impl Debug for Batch

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<Q: IntoQuad> Extend<Q> for Batch

fn extend<I>(&mut self, iter: I) where
    I: IntoIterator<Item = Q>, 

Extends a collection with the contents of an iterator.

impl<Q: IntoQuad + Send> ParallelExtend<Q> for Batch

Extends the Batch using a parallel iterator from rayon.

If you are dealing with many thousands of quads, par_extend can help you speed up your drawing by using multiple threads to populate a Batch.

fn par_extend<I>(&mut self, par_iter: I) where
    I: IntoParallelIterator<Item = Q>, 

Extends an instance of the collection with the elements drawn from the parallel iterator par_iter.
