Reduce Allocations

[Nerixyz]

Especially when parsing IRC messages, a lot of Strings are created that are really just substrings of the original message, so a &str would be more efficient. This would make the message struct tied to a lifetime (of the backing String) making it hard to move the struct around. However, there are crates out there that would make this simpler, like yoke.

I think it's worth at least discussing this.

Also see this article on yoke: Not a Yoking Matter (Zero-Copy #1).

I think you're right, that would make a lot of sense. I hadn't heard of yoke, actually. When I last looked into it, self-referential structs were a royal pain in the ass.

It may be possible to partially get around this by using inline strings. Something like [SmartString] or [compact_str] may work. It wont be a lot (24 bytes at most) but it's better than nothing.

Mentioning fast-str here as well.
