manta-cli 2.0.0-beta.63

//! Implements the `manta get hardware group` command.
//!
//! Hits `GET /groups/hardware` on `manta-server` to return the
//! aggregated hardware inventory of an HSM group. Output defaults to
//! the `summary` view from [`crate::output::hardware::print_cluster`];
//! pass `--output` for an alternative view. See
//! [`super::hardware_nodes`] for the per-node variant.
