Serializing fixed-size arrays in serde
View serde-byte-array.md

Summary

Add the following method to Serializer:

fn serialize_byte_array<const N: usize>(self, bytes: &[u8; N]) -> Result<Self::Ok, Self::Error> {
    self.serialize_bytes(bytes)
}

Using cargo features to replace a set of concrete trait impls with a blanket one

There's subtlety involved in doing this so I've just dumped this out from another document in case I ever need to remember what they were in the future.

value::Visit

The Visit trait can be treated like a lightweight subset of serde::Serialize that can interoperate with serde, without necessarily depending on it. It can't be implemented manually:

/// A type that can be converted into a borrowed value.
