Select commented-out lines?

[max-sixty]

Often I'll comment out some lines, and then want to uncomment them. Currently I manually select the lines, which is often kkVjjjjj.

If there's are empty lines at the start and end of the block, this can be {V}, but I'm always that fortunate / planful.

Is there any way of selecting the lines with a keybinding?

The rule would be "Any contiguous line that begins with // (or whatever the comment string is)". For example, assuming the cursor is in the middle of the block, is it possible to select the commented out section?

pub struct IdentParts {
    pub parts: Vec<String>,
}
// impl std::fmt::Display for IdentParts {
//     fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
//         display_ident_parts(f, self)
//     }
// }
impl IdentParts {
    pub fn from_path<S: ToString>(mut path: Vec<S>) -> Self {
        let name = path.pop().unwrap().to_string();

This works for comments that start with // and #. Explanation:

    // Selects single-line comments blocks, starting with `#` or `/`
    // <g;> doesn't expand over blank lines, <g:> does
    // We have to write out the whole regex in single characters, which makes it
    // illegible, unfortunately. But the regex is:
    // - `^(\\s*[^\\s#/])` for `<g:>`
    // - `^(\\s*[^\\s#/]|$)` for `<g;>`
