For past releases the freeze happened around January[0] for toolchain and other key packages[1] (these are frozen first, since any bigger changes there obviously have a lot of knock-on effects in the rest of the packages/archive).

None if has yet been finalized/announced for the upcoming Trixie release, but I expect that rustc/cargo will be part of the set of key packages again (compared to the Bookworm release, their usage is even more widespread after all! :)), that those will be frozen first again, and that the rough timeline give or take a few weeks will be similar to that of Bookworm. The historic trend goes towards shorter freezes.

Obviously, under the condition that the release team has no objections :)

Following up on this: with recent Debian discussions on Trixie freeze
plans, do you still expect that shipping 1.85 beta and following up with
the released version will be possible?

Our offer to help with any issues that arise still stands. Please let us
know if there's anything we can do to help Trixie ship with Rust 1.85
and the Rust 2024 edition. We have various developers (e.g. folks
working on Rust in the Linux kernel) asking us and crossing their
fingers that Debian stable will work for their development for a while.
