Function graphalgs::connect::has_path_connecting

pub fn has_path_connecting<G>(
    g: G,
    from: <G as GraphBase>::NodeId,
    to: <G as GraphBase>::NodeId,
    space: Option<&mut DfsSpace<<G as GraphBase>::NodeId, <G as Visitable>::Map>>
) -> boolwhere
    G: IntoNeighbors + Visitable,

[Generic] Check if there exists a path starting at from and reaching to.

If from and to are equal, this function returns true.

If space is not None, it is used instead of creating a new workspace for graph traversal.
