[$] Defining the Rust 2024 edition

In December, the Rust project released

a call for proposals for inclusion in the 2024 edition. Rust handles
backward incompatible changes by using
Editions,
which permit projects to specify a single stable edition for their code
and allow libraries written
in different editions to be linked together. Proposals for Rust 2024 are
now in, and have until the end of February to be debated and decided on. Once
the proposals are accepted, they have until May to be implemented in time for
the 2024 edition to be released in the second half of the year.
