normalize_event_name() allocates a lowercase String for matching (to_ascii_lowercase) and then allocates again for the returned String (even in the non-shorthand _ case). This does unnecessary work for a CLI parse path; consider avoiding the temporary allocation by matching with eq_ignore_ascii_case (or matching on ASCII bytes) and only allocating the output once.

Suggested change
match value.to_ascii_lowercase().as_str() {
"put" => "s3:ObjectCreated:*".to_string(),
"get" => "s3:ObjectAccessed:*".to_string(),
"delete" => "s3:ObjectRemoved:*".to_string(),

"ilm" => "s3:ObjectTransition:*".to_string(),
_ => value.to_string(),
