Struct pbrt::blockqueue::BlockQueue

pub struct BlockQueue { /* fields omitted */ }

The queue of blocks to be worked on shared immutably between worker threads.

Methods

impl BlockQueue

pub fn new(     img: (u32, u32),     dim: (u32, u32),     select_blocks: (usize, usize) ) -> BlockQueue

Create a block queue for the image with dimensions img. Panics if the image is not evenly broken into blocks of dimension dim

pub fn block_dim(&self) -> (u32, u32)

Get the dimensions of an individual block in the queue

Important traits for BlockQueueIterator<'a>

impl<'a> Iterator for BlockQueueIterator<'a> type Item = (u32, u32);

pub fn iter(&self) -> BlockQueueIterator

Get an iterator to work through the queue

pub fn next(&self) -> Option<(u32, u32)>

Get the next block in the queue or None if the queue is finished

pub fn len(&self) -> usize

Get the length of the queue

pub fn is_empty(&self) -> bool

Check if the queue is empty
