Module probe 

SSH host probing for remote source setup.

This module provides functionality to probe SSH hosts and gather comprehensive information needed for remote source configuration decisions:

• Whether cass is installed (and what version)
• Index status (session count)
• Detected agent session data directories
• System information (OS, architecture)
• Resource availability (disk space, memory)

Design

Probing uses a single SSH session per host to minimize latency. A bash probe script is piped to bash -s on the remote, gathering all information in one round-trip.

Example

use coding_agent_search::sources::probe::{probe_host, probe_hosts_parallel};
use coding_agent_search::sources::config::DiscoveredHost;

// Single host probe (returns HostProbeResult directly, not Result)
let host = DiscoveredHost { name: "laptop".into(), .. };
let result = probe_host(&host, 10);
if result.reachable {
    println!("Connected in {}ms", result.connection_time_ms);
}

// Parallel probing with progress (synchronous, uses rayon internally)
let results = probe_hosts_parallel(&hosts, 10, |done, total, name| {
    println!("Probing {}/{}: {}", done, total, name);
});

Structs

DetectedAgent

Detected agent session data on a remote host.

HostProbeResult

Result of probing an SSH host.

ProbeCache

Cache for probe results to avoid repeated probing.

ResourceInfo

Resource information for installation feasibility.

SystemInfo

System information gathered from remote host.

Enums

CassStatus

Status of cass installation on a remote host.

Constants

DEFAULT_PROBE_TIMEOUT

Default connection timeout in seconds.

Functions

deduplicate_probe_results

Deduplicate probe results that point to the same physical machine.

probe_host

Probe a single SSH host.

probe_hosts_parallel

Probe multiple hosts in parallel.
