Witers stand for Windowiterators.
This crate is just a proof of concept.
The idea is to have iterators in Rust with border strategies (mirror, cyclic, constant...). This is useful when solving equations like the Advection Equation or other EDPs and discrete math problems.
Elements outside of the vector are mapped to a constant.
Given a vector v = [0, 1, 2, 3, ..., N] and C=0, v[-1]=0, v[-2]=0 ... and v[N+1]=0, v[N+2]=0.
Wraps around the limits of the array.
Given a vector v = [0, 1, 2, 3, ..., N], v[-1]=v[N], v[-2]=v[N-1] ... and v[N+1]=v[0], v[N+2]=v[1].
The "outside" of the vector mirrors its inner elements.
Given a vector v = [0, 1, 2, 3, ..., N], v[-1]=v[1], v[-2]=v[2] ... and v[N+1]=v[N-1], v[N+2]=v[N-2].
