A second-rack bagel that's nearly first-rack. Tasty stuff.
Summary
The article introduces a programming idiom called the "block pattern" in Rust, which leverages Rust's feature that blocks are valid expressions. The author explains how this pattern can make Rust code cleaner and more robust by showing equivalent code examples that demonstrate how blocks can be used as expressions to simplify code structure and improve readability. The pattern is presented as a useful but under-discussed idiom that the author frequently uses in their own Rust programming.
Key quotes
· 4 pulledHere's a little idiom that I haven't really seen discussed anywhere, that I think makes Rust code much cleaner and more robust.
I don't know if there's an actual name for this idiom; I'm calling it the 'block pattern' for lack of a better word.
I find myself reaching for it frequently in code, and I think other Rust code could become cleaner if it followed this pattern.
The pattern comes from blocks in Rust being valid expressions.
