Struct FrameSet

Source

pub struct FrameSet { /* private fields */ }

Expand description

A pool of reusable framebuffer image IDs allocated for a buffer collection.

Implementations§

Source §

impl FrameSet

Source

pub fn new(available: BTreeSet<ImageId>) -> FrameSet

Source

pub fn take_image(&mut self) -> Option<ImageId>

Removes and returns the first available image ID, or None if empty.

Source

pub fn return_image(&mut self, image_id: ImageId)

Inserts the returned image ID back into self.available.

image_id must be one of the IDs previously returned by take_image.

Source

pub fn no_images_in_use(&self) -> bool

Returns true if all images allocated for this pool are available.

Source

pub fn image_count_for_testing(&self) -> usize

Returns the total number of images in the pool.

Source

pub fn available_count_for_testing(&self) -> usize

Returns the number of currently available images in the pool.
