imgref-iter

A small crate for iterating over the rows or columns of imgref buffers.

This crate exports four traits that allow creating iterators over rows or columns of imgref::Imgs:

• ImgIterPtr for Img<*const [T]>; allows creating iterators over *const pointers

• ImgIterPtrMut for Img<*mut [T]>; allows creating iterators over *mut pointers

• ImgIter for Img<&[T]>; allows creating iterators over shared references

• ImgIterMut for Img<&mut [T]>; allows creating iterators over mutable references

Methods on ImgIterPtr and ImgIterPtrMut are unsafe because they offset on the provided pointers. ImgIter and ImgIterMut cannot include safe versions because the pointer iterators may outlive the references.

See the documentation for more information.
