Struct AddDir 

pub struct AddDir {
    pub host_path: String,
    pub guest_path: String,
    pub read_only: bool,
}

One --add-dir host:guest[:mode] mapping.

The host directory is materialized into a small ext4 image attached as an extra Firecracker drive, then mounted at guest_path by a wrapper script before the user’s command runs. When read_only is false (mode :rw), guest writes land in the ext4 image and are rsynced back to the host directory after the command exits — see ADR-002.

Fields

host_path: String

guest_path: String

read_only: bool

Implementations

impl AddDir

pub fn parse(spec: &str) -> Result<Self>

Parse a host:guest[:mode] spec.

The first colon splits host from guest. An optional trailing :ro or :rw selects the mount mode (default :ro). Other trailing tokens that look like a mode (no slash, alphanumeric) are rejected to catch typos. Guest paths that legitimately contain colons remain supported as long as the trailing component is unambiguously path-shaped (contains a slash).

Trait Implementations

impl Clone for AddDir

fn clone(&self) -> AddDir

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AddDir

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AddDir

fn eq(&self, other: &AddDir) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
