This crate provides a Canvas struct that is constructed of a single vector, but act as a 2 dimensional matrix. Along with the struct are functions to access its elements by row and column, as well as access to iterators over all elements.
I needed a simple struct to act as a 2 dimensional array, mostly for image creation and manipulation. After some testing, I found that using a single vector, as opposed to a vector of vector, is faster, even with the added operations needed to abstract away the access by column and row. This crate provides just this.
