Module rad::rados [−] [src]

Wrappers for Ceph cluster connections, Ceph I/O contexts, and associated operations.

Connection building example

The following example connects to a Ceph cluster using the ceph.conf file at /etc/ceph/ceph.conf, as the admin user, and setting the RADOS config keyring option to the value of /etc/ceph/ceph.client.admin.keyring (which is necessary for connecting to Ceph using config files/keyrings located on nonstandard paths.)

use std::path::Path;
use rad::ConnectionBuilder;

let mut cluster = ConnectionBuilder::with_user("admin")?
                  .read_conf_file(Path::new("/etc/ceph/ceph.conf"))?
                  .conf_set("keyring", "/etc/ceph/ceph.client.admin.keyring")?
                  .connect()?;

Connection	A wrapper over a connection to a Ceph cluster.
ConnectionBuilder	A wrapper around a `rados_t` providing methods for configuring the connection before finalizing it.
Context	A wrapper around a `rados_ioctx_t`, which also counts as a reference to the underlying `Connection`.
