Rust specific ligatures

[Rhelvetican]

I would like to request ligatures for Rust for the following symbols:

• #[]
• ::<>

Hi, I love getting requests for new ligatures! 😄 I'm not familiar with Rust, so just to confirm, these are both examples of opening/closing tags that would usually have other text placed between the brackets, right? So the ligature part would only be #[ and ::<, respectively? And what is the expected appearance of both of these ligatures? I assume it would be the # horizontal lines extending to the right to connect with the edge of the bracket, and the :: shifting upward to align vertically with <?
