Struct WriteScope 

pub struct WriteScope { /* private fields */ }

The directories a run may write into.

Implementations

impl WriteScope

pub fn new( root: &Path, cwd: &Path, shared_dirs: Vec<PathBuf>, ) -> Result<Self, String>

Build the scope for a project root.

The Git work tree that contains the root counts only when cwd is inside it too. That is the monorepo case the allowance exists for. It keeps a Git repository at $HOME (a dotfiles setup) from allowing every home path to a run started outside that tree.

Errors

Returns a message when the root cannot be resolved, so a caller fails closed.

pub fn contains(&self, path: &Path) -> bool

Whether a resolved path lies inside one of the allowed directories, or is an existing character device or named pipe.

pub fn check(&self, flag: &str, path: &Path, cwd: &Path) -> Option<String>

Return an error message when path, relative to cwd, resolves outside the allowed directories. flag names the option that asked for the write.
