Peeking inside a Rust enum
During a recent Rust Q&A Session on my twitch
channel, someone asked a question that
seemed simple: why are small string types, like SmartString or SmolStr,
the same size as String, but small vec types, like SmallVec, are larger
than Vec?
Now I know I just used the adjective simple, but the truth of the matter is: to understand the question, we’re going to need a little bit of background.
