pub struct SimpleAtlasAllocator { /* fields omitted */ }

A simpler atlas allocator implementation that can allocate rectangles but not deallocate them.

Implementations

impl SimpleAtlasAllocator

pub fn new(size: Size) -> Self

Create a simple atlas allocator with default options.

pub fn with_options(size: Size, options: &AllocatorOptions) -> Self

Create a simple atlas allocator with the provided options.

pub fn clear(&mut self)

Drop all rectangles, clearing the atlas to its initial state.

pub fn reset(&mut self, size: Size, options: &AllocatorOptions)

Clear the allocator and reset its size and options.

pub fn is_empty(&self) -> bool

pub fn size(&self) -> Size

The total size of the atlas.

pub fn allocate(&mut self, requested_size: Size) -> Option<Rectangle>

Allocate a rectangle in the atlas.

pub fn grow(&mut self, new_size: Size)

Resize the atlas without changing the allocations.

This method is not allowed to shrink the width or height of the atlas.

pub fn init_from_allocator(&mut self, src: &AtlasAllocator)

Initialize this simple allocator with the content of an atlas allocator.
