Rust Meetup Reboot 3

The first Rust meetup after another long period of absence. Once again hosted at Quantinuum's office on Hill's road.

Our speaker will be Agustín Borgna (https://github.com/ABorgna), one of the maintainers of the popular petgraph library!

Topic: Evolving an old rust crate by breaking things

`petgraph` came out in January 2015, before Rust version 1.0. The language has greatly changed since then, and the must evolve with it.

How does one update a widely used crate without breaking everyone's code?

I'm also hoping to have a bit of open discussion about the future of the meetup page as I (John) haven't found the time and energy to host meetups recently. If anyone is interested in becoming an organiser or taking over the group, please get in contact.
