Daily Rust: Iterators

Tue, 24 Aug 2021 03:55:00 +0800

Iterators are part of Rust’s secret sauce. They power things from the humble for-loop to the elegant iterator chain, but have you ever stopped to think how they work?

Let’s find out more about Rust’s iterators by implementing our own versions of common iterators and reading the standard library’s source code.

Daily Rust: Slice Patterns

Sat, 14 Aug 2021 00:00:00 +0000

Rust 1.26 introduced a nifty little feature called Basic Slice Patterns which lets you pattern match on slices with a known length. Later on in Rust 1.42 , this was extended to allow using .. to match on “everything else”.

As features go this may seem like a small addition, but it gives developers an opportunity to write much more expressive code.
