What is if let in Rust used for?

Quick pattern matching without full match — ideal for single-case Options or Results.

if let vs match in Rust: when to use which?

if let for brevity on one pattern; match for exhaustive multi-arm safety.

Yep — guards, or-patterns, but keep it simple or revert to match.

Rust devs dreaded verbose match blocks for simple checks. if let flips the script — concise, powerful, and a breath of fresh air for control flow.
