I was surprised to learn the extent of what is a valid local-part (something+else in your example) of an email. Can have two dots in sequence if the local-part is quoted, and support for non alphanumeric characters like !#$%&'*+-/=?^_`{|}~; if the local-part is quoted, comments with parentheses. And it could be case sensitive.
- WirelessGigabit 3y agoWe have the following validation: let form_email: Option::<String> = /* ... */; match form_email { Some(email) if !email.is_empty() => { // ... send email with validation link }, _ => { // report missing email } } If you (can) click the validation link it's a valid email. If not... it's invalid. Saves me the trouble of debugging all the regexes.
