MountRoot

adk_rust::code::embedded_python::monty_fs

Struct MountRoot 

Source 
pub struct MountRoot { /* private fields */ }
Available on crate features code and embedded-python only.
Expand description

A host directory opened once, mountable as often as the host likes; cloning shares the descriptor.

Reuse one instead of re-deriving a mount from its path: sandbox code that can rename inside a parent mount redirects that name between rebuilds, and an open descriptor cannot be redirected.

Implementations§

Source§

impl MountRoot

Source

pub fn open( virtual_path: &str, host_path: impl AsRef<Path>, ) -> Result<MountRoot, MountError>

Opens host_path, pinning the root to the directory that is there now.

§Errors

Returns MountError::InvalidMount if the virtual path is not absolute, or the host path cannot be opened as a directory or canonicalized.

Source

pub fn virtual_path(&self) -> &str

Returns the normalized virtual path prefix this root answers on.

Source

pub fn host_path(&self) -> &Path

Returns the canonical host directory path. Diagnostics only.
