Description
I tried this code:
find(line.to_string(), &cap[0]).iter().for_each(|x| {
#[allow(clippy::cast_possible_truncation)]
coordinates.push((*x as u16, i as u16));
})
*line = replace;I expected to see this error happen: Missing semicolon at the end of statement
Instead, these two errors happened:
error[E0070]: invalid left-hand side of assignment
error[E0369]: cannot multiply `&mut String` to `()`
