//! # `LibStorageMgmt`
//!
//! `LibStorageMgmt` provides a set of API for programmatically manage their
//! storage hardware in a vendor neutral way supporting these actions:
//!
//!  * List storage pools, volumes, access groups, or file systems.
//!
//!  * Create and delete volumes, access groups, file systems, or NFS exports.
//!
//!  * Grant and remove access to volumes, access groups, or initiators.
//!
//!  * Replicate volumes with snapshots, clones, and copies.
//!
//!  * Create and delete access groups and edit members of a group.
//!
//!  * List Linux local SCSI/ATA/NVMe disks.
//!
//!  * Control IDENT/FAULT LED of local disks via SES(SCSI Enclosure Service), NPEM, VMD (utilizes ledmon library)
//!
//! To use `LibStorageMgmt` rust binding, you need:
//!
//!  * Start the libstoragemgmt daemon(`lsmd`)
//!
//!  * Choose a URI after reading [`LibStorageMgmt` user guide][1]
//!
//!  * Make a connection to plugin via [`lsm::Client`][2].
//!
//!  * Check required [`lsm::Capabilities`][3] for supported functionality.
//!
//!  * Invoke required method of [`lsm::Client`][2].
//!
//! # Example code using simulator plugin
//!
//! ```rust
//! extern crate lsm;
//! use lsm::{Client, LsmError};
//!
//!     let mut c: Client = match Client::new("sim://", None, None) {
//!         Ok(i) => i,
//!         Err(e) => {
//!             match e {
//!                 // Error handling goes here
//!                 LsmError::DaemonNotRunning(_) =>
//!                     panic!("Please start the libstoragemgmt daemon"),
//!                 _ => panic!("{}", e)
//!             };
//!         },
//!     };
//!     let syss = match c.systems() {
//!         Ok(i) => i,
//!         Err(e) => panic!("{}", e)         // Please use error handling as above.
//!     };
//!     for s in syss {
//!         let cap = match c.capabilities(&s) {
//!             Ok(i) => i,
//!             Err(e) => panic!("{}", e)     // Please use error handling as above.
//!         };
//!         if cap.is_supported(lsm::Capability::Volumes) {
//!             let vols = match c.volumes() {
//!                 Ok(i) => i,
//!                 Err(e) => panic!("{}", e) // Please use error handling as above.
//!             };
//!             for vol in vols {
//!                 println!("Got volume: {} {}", vol.name, vol.id);
//!             }
//!         }
//!     }
//!
