Borrow checker errors like E0382 occur when code violates Rust's ownership rules—typically moving a value twice or using it after a move. Paste your compiler error and I'll diagnose the specific violation, identify whether it's an ownership, borrowing, or lifetime issue, and route you to the appropriate fix while preserving code semantics.

Lifetimes are Rust's way of tracking how long references are valid. Compile errors arise when a reference outlives the data it points to or when lifetime relationships between function parameters and return values aren't explicitly declared. I help diagnose these errors and guide you through adding or adjusting lifetime annotations.

Ownership problems occur when code tries to use a moved value or borrows incompatibly. I analyze your error, determine whether you need to clone, use references, adjust lifetimes, or restructure borrowing patterns, then provide concise fixes that solve the compile error without unnecessary clones or semantic changes.

Yes. Paste your compiler error output and I'll explain the borrow checker violation, identify the ownership pattern causing it—whether E0502, E0597, or another error—and break down the semantics so you understand both the fix and the underlying rule Rust is enforcing.

A move occurs when Rust transfers ownership of a value to a new binding; the original binding becomes invalid. Move errors happen when code tries to use a value after it's been moved elsewhere. I help identify where the move happens, whether you need borrowing instead, and how to restructure code to keep values in scope.
