euralios_std/src/path.rs:239–247

Truncates `self` to [`self.parent`]. Returns `false` and does nothing if [`self.parent`] is [`None`]. Otherwise, returns `true`. [`self.parent`]: Path::parent # Examples ``` use std::path::{Path, PathBuf}; let mut p = PathBuf::from("/spirited/away.rs"); p.pop(); assert_eq!(Path::new("/spirited"), p); p.pop(); assert_eq!(Path::new("/"), p); ```

(&mut self)

    /// assert_eq!(Path::new("/"), p);
    /// ```
    pub fn pop(&mut self) -> bool {
        match self.parent().map(|p| p.as_u8_slice().len()) {
            Some(len) => {
                self.as_mut_vec().truncate(len);
                true
            }
            None => false,
