* Add distance_matrix to rustworkx-core This commit moves the distance matrix functionality to rustworkx. This is mostly a straightforward migration as the functionality was written in a generic way already. The only difference is how node holes were handled, the this opted to split the functions into 2, a verison that assumes the graph has compact indices and one that doesn't. * Optimize the implementation of distance matrix This commit performs some optimizations on the internals of the distance_matrix() function. It avoids extra allocations and uses a fixedbitset for tracking instead of hashsets. Co-authored-by: Jake Lishman <[email protected]> * Deduplicate functions * Add release note * Remove stray debug print * Remove invalid classifier and capitalize keywords * Bump release version to 0.17.1 --------- Co-authored-by: Jake Lishman <[email protected]> Co-authored-by: Ivan Carvalho <[email protected]> Co-authored-by: Ivan Carvalho <[email protected]> (cherry picked from commit 7318a80)
