…kit#1195) In the recently merged Qiskit#1192 a new generic DAG longest_path function was added to rustworkx-core. However, the trait bounds on the function were a bit tighter than they needed to be. The traits were forcing NodeId to be of a NodeIndex type and this wasn't really required. The only requirement that the NodeId type can be put on a hashmap and do a partial compare (that implements Hash, Eq, and PartialOrd). Also the IntoNeighborsDirected wasn't required because it's methods weren't ever used. This commit loosens the traits bounds to facilitate this. At the same time this also simplifies the code structure a bit to reduce the separation of the rust code structure in the rustworkx crate using longest_path().
This commit migrates the .cargo/config file which has been deprecated to the new path .cargo/config.toml. This will fix warnings that are emitted when compiling with the latest stable release. This new path has been supported since Rust 1.38 which is much older than our current MSRV of 1.70.

We never released the code so you don’t have to include release notes this time

* add hyperbolic random graph model generator * Loosen trait constraints and simplify structure for longest_path (Qiskit#1195) In the recently merged Qiskit#1192 a new generic DAG longest_path function was added to rustworkx-core. However, the trait bounds on the function were a bit tighter than they needed to be. The traits were forcing NodeId to be of a NodeIndex type and this wasn't really required. The only requirement that the NodeId type can be put on a hashmap and do a partial compare (that implements Hash, Eq, and PartialOrd). Also the IntoNeighborsDirected wasn't required because it's methods weren't ever used. This commit loosens the traits bounds to facilitate this. At the same time this also simplifies the code structure a bit to reduce the separation of the rust code structure in the rustworkx crate using longest_path(). * use vector references * change to slice (clippy) * generalize to H^D, improve numerical accuracy * allow infinite coordinate * handle infinity in hyperbolic distance * remove unused import (clippy) * fix python stub * Rename deprecated cargo config file (Qiskit#1211) This commit migrates the .cargo/config file which has been deprecated to the new path .cargo/config.toml. This will fix warnings that are emitted when compiling with the latest stable release. This new path has been supported since Rust 1.38 which is much older than our current MSRV of 1.70. * fix hyperbolic distance, swap r and beta, infer time coordinate * use mul_add in hyperbolic distance, remove release note * replace clone with dereference --------- Co-authored-by: Matthew Treinish <mtreinish@kortar.org> Co-authored-by: Ivan Carvalho <8753214+IvanIsCoding@users.noreply.github.com> Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>

The hyperbolic distance returned NaN for very close vertices. This meant the hyperbolic geometric graph generator wouldn't create edges that should exist.
I realized it didn't make sense to accept infinite coordinates (hyperbolic distance is undefined in most cases) and return an error instead.
I swapped the order of the parameters in the rustworkx-core api to match the rustworkx api.
Finally, it's inconvenient to specify the time coordinates since it can be computed using the other coordinates. Users only need to specify the useful coordinates.
