manta-cli 2.0.0-beta.67

//! Implements the `manta add nodes` command.
//!
//! Assigns the xnames matching a host expression to an existing HSM
//! group via `POST /api/v2/groups/{label}/members`. Shows an
//! interactive confirmation prompt unless `--assume-yes` is set.
//! `--dry-run` prints what *would* happen and returns without calling
//! the server. Sibling of [`super::group`] (which can also seed
//! initial members at creation time) and inverse of
//! [`super::super::delete::nodes`].
