cell, proto: Use correct Data sizes for v1 relay cells

2025-04-16T14:58:49Z

Since v1 cells have a longer tag, they can fit less data into a single cell. Ah well, that's the cost of improved security. The code in data.rs is a little wonky, in that it currently requires its buffer to be exactly the maximum size for a data cell. We have a TODO about fixing that in the future, but for now I've moved it to use a boxed slice rather than a boxed array. Part of #1944.

Note some places where we need updates for #1944.

(Also note a couple of other CGO-related issues)

Some HasMemoryCost impls in tor-cell

Change tor_bytes::Error::BadMessage to a Cow.

2023-02-09T15:20:31Z

Actually, to avoid making a breaking change, I'm deprecating BadMessage and creating a new InvalidMessage variant that takes a Cow. This way I don't need to track every crate that re-exposes tor_bytes::Error and call this a breaking change in those. Making this change will allow tor_bytes errors to be much more helpful.

tor-cell: Have restrict_msg add conversion functions.

Every FooMsg type now implements Into, and TryFrom. Additionally, it now implements From for every distinct type that it supports. This last part lets us discard a bunch of code. Unfortunately, I needed some downright hackish trickery in order to get these macros to avoid generating `From for AnyFooMsg` and conflicting with the blanket implementation. The trickery to deal with RelayEarly and Relay being the same type was not necessarily worth it; I will be separating them and removing said trickery in the next commit.

tor-cell: Rename RelayMsg and RelayCell-related types.

Thanks to rust-analyzer for making this simple.

tor-cell: Make Body and MsgClass traits more uniform.

2023-02-07T21:03:14Z

Doing this will make it much easier to implement a macro that generates restricted instances of the Msg types (for #525). The Body change is a breaking change. I don't think anybody else implements Body, but in theory they could.

tor-cell: Stop using write_infallible

2022-07-11T15:18:51Z

Also, stop using "expect" and "assert!" to check for errors.

tor-cell: Make encoding method signatures fallible.

2022-07-11T15:18:51Z

Convert each write_onto_infallible implementation into write_onto.
