Enum Backend 

pub enum Backend {
    None,
    Bwrap,
    Docker,
}

How commands are confined.

Variants

None

Run directly, as you, with your credentials. The historical behaviour, and the only sane default for a supervised CLI on a machine where the alternatives may not be installed.

Bwrap

User namespaces via bwrap. Cheap — no daemon, a few milliseconds — and the right choice where unprivileged user namespaces are permitted.

Docker

A throwaway container. Works where user namespaces are locked down, costs a container start per command.
