Note that all cryptographic primitives are still going to be in C via an OpenSSL-like API for the next while; the current proposal is to migrate from OpenSSL to one of its forks. Various bits of backend logic that aren't cryptographic primitives (e.g., parsing) have been rewritten in Rust; additionally, https://github.com/ctz/graviola is mentioned near the end as a possible implementation of cryptographic primitives in a combination of Rust and assembly (without any C), but it's not especially mature yet.
Whatever happened to libsodium that was designed to provide vetted cryptographic primitives with a modern API? https://doc.libsodium.org/doc
libsodium is great if you only need to interoperate with other software using libraries that sound like “sodium”. This is generally not helpful for the kinds of things that people use OpenSSL for.
Still great, but the primitives it provides aren't necessarily the ones you need.
