igraph weighted adjacency() requires attribute handler to store weights, inconsistent with other functions

igraph weighted adjacency() requires attribute handler to store weights, inconsistent with other functions: a task in LegoFlow-SWE (Harbor dataset). The igraph weighted adjacency() function currently forces callers to set up the attribute handler before edge weights can be retrieved. This is not…

The task

The `igraph_weighted_adjacency()` function currently forces callers to set up the **attribute handler** before edge weights can be retrieved. This is not required by most other igraph functions and creates an unnecessary hurdle, especially for newcomers who shouldn’t need to learn the attribute handler system just to…
