Review this generated record lookup helper.
Find a key in semicolon-separated fields, return an optional zero-copy view into record, permit temporary key and delimiter arguments, trim Unicode whitespace, allocate nothing, and produce no output.
Rust
fn lookup_value<'a>(
record: &'a str,
key: &'a str,
delimiter: &'a str,
) -> &'a str {
println!("record={record}");
let owned = record.to_string();
for field in owned.split(';') {
if let Some((candidate, value)) = field.split_once(delimiter) {
if candidate.trim_ascii() == key {
return value.trim_ascii();
}
}
