On: A half-hour to learn Rust

[mlthoughts2018]

Yeah, when reading this I was wondering if Rust has sealed traits like Scala, and also structural typing.

The extreme degree of shared syntax and shared semantics with Scala was really surprising to me.

[steveklabnik → mlthoughts2018]

Rust does not have sealed traits, though you can sorta contort the privacy system to do similar things if you want. We also do not have structural typing. (Generally; tuples are structurally typed but nothing else is)

A lot of Rust’s language people did a lot in Scala. The language’s are pretty different IMHO.

[nobleach → steveklabnik]

As was explained to me, Rust has heritage from OCaml. If one squints, they can even see it still beneath the surface. I hear the original compiler was even written in OCaml.

[steveklabnik → nobleach]

Yes, especially amongst the earliest folks, there was a lot of OCaml, and the original compiler was, yes.
