Struct BwrapCmd 

pub struct BwrapCmd<'a> {
    chroot_path: Cow<'a, Utf8Path>,
    bind_mounts: Vec<(&'a str, &'a str)>,
    env_vars: Vec<(&'a str, &'a str)>,
}

Builder for running commands inside a target directory using bwrap.

Fields

chroot_path: Cow<'a, Utf8Path>

The target directory to use as root for the container

bind_mounts: Vec<(&'a str, &'a str)>

Bind mounts in format (source, target)

env_vars: Vec<(&'a str, &'a str)>

Environment variables to set

Implementations

impl<'a> BwrapCmd<'a>

pub fn new_with_dir(path: &'a Dir) -> Self

Create a new BwrapCmd builder with a root directory as a File Descriptor.

pub fn new(path: &'a Utf8Path) -> Self

Create a new BwrapCmd builder with a root directory

pub fn bind( self, source: &'a impl AsRef<Utf8Path>, target: &'a impl AsRef<Utf8Path>, ) -> Self

Add a bind mount from source to target inside the container.

pub fn setenv(self, key: &'a str, value: &'a str) -> Self

Set an environment variable for the command.

pub fn set_default_path(self) -> Self

Set $PATH to a reasonable default for finding system binaries.

The bwrap environment may not have a complete $PATH, causing tools like bootupctl or sfdisk to not be found. This sets a default that covers the standard binary directories.

fn build_command<S: AsRef<OsStr>>( &self, args: impl IntoIterator<Item = S>, ) -> Command

Build the bwrap Command with all bind mounts, env vars, and args.

pub fn run<S: AsRef<OsStr>>( self, args: impl IntoIterator<Item = S>, ) -> Result<()>

Run the specified command inside the container.

pub fn run_get_string<S: AsRef<OsStr>>( self, args: impl IntoIterator<Item = S>, ) -> Result<String>

Run the specified command inside the container and capture stdout as a string.

Trait Implementations

impl<'a> Debug for BwrapCmd<'a>

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

Formats the value using the given formatter.
