Struct PlaygroundGuard 

pub struct PlaygroundGuard { /* private fields */ }

Guard that keeps real-mode lesson commands inside the playground.

Implementations

impl PlaygroundGuard

pub fn new(root: impl Into<PathBuf>) -> Self

Create a guard for the given playground root (absolute path).

pub fn check(&self, command: &str, cwd: &Path) -> GuardVerdict

Check a command line before it is sent to the real shell.

cwd is the tracked working directory for the practice session; it must be inside the playground root. The check is purely lexical — it never touches the filesystem.
