Update substring match for substitutions #148061

faculerena · 2025-10-24T05:42:58Z

Fixed as_substr function to check for matching prefixes too. This fixes this issue where td::s is matched instead of std::. This same behaviour can be seen with time and tokio::time and similar cases where the error import starts with the same prefix as the suggestion.

use sync;
fn main() {}

After the changes:
