bitcoin: simplify logic replacing match block
What changed, and why it matters
This is a minor code cleanup in the rust-bitcoin library. A developer replaced a verbose match block with the shorter `?` operator, which does the exact same thing in Rust: if an error occurs, return it immediately; otherwise continue. There is no functional change and no security impact.
No action needed. This is a safe, non-functional refactoring.
Security signals we found
No strong security signals were identified.
Evidence from the diff
In bitcoin/src/bip158.rs, the BlockFilterWriter::add_element loop used an explicit match to propagate errors from script_for_coin. The patch replaces it with let script = script?;, which is semantically equivalent. This is a pure refactoring that reduces line count and improves readability without altering control flow, error handling, or behavior.
