Fields

auth_key: String

lan_key: String

A separate, narrowly-scoped credential for LAN peer discovery (mDNS TXT record + UDP broadcast responder) — NOT auth_key. Minted fresh per-launch, internal to srv only (never needs to leave this process except via the LAN broadcast itself, unlike auth_key which the launcher/frontend also need — see LanDiscovery’s doc comment). Broadcasting the full-access auth_key to anything that can receive an mDNS multicast packet or send a UDP probe used to mean a passive LAN listener got standing access to the ENTIRE local /agentmux/service surface, not just LAN-forwarding — this key is accepted only by the two routes LAN peer forwarding actually needs (lan_or_full_auth_middleware in server/mod.rs), so a captured value’s blast radius shrinks to “can forward jekts to this instance and query which agents live here.”

host_reg_secret: Option<String>

Shared secret proving a host_ipc.Register caller is really the paired CEF host, not an agent process (agents share auth_key too — see host_ipc.rs::handle_register’s doc comment). None when nobody set AGENTMUX_HOST_REG_SECRET — handle_register then refuses every registration rather than accepting one unauthenticated, since there’s nothing to check the caller against. Sourced from the launcher (agentmux-launcher::srv_spawner::SrvSpawnResult::host_reg_secret, minted once and reused across host-only crash-restarts, exactly like auth_key) or, in host-owned-spawn/dev mode, from the host itself (crates/cef/src/sidecar.rs::spawn_backend, which generates it alongside its own auth_key).

data_home: PathBuf

Empty when unset. Paths stay PathBuf (read with var_os) so a home directory that isn’t valid UTF-8 still reaches the stores intact (Codex P2 on #3893).

config_home: PathBuf

app_path: String

is_dev: bool

version: &'static str

build_time: &'static str

instance_id: String

Implementations

impl Config

pub fn from_env_and_args(args: &CliArgs) -> Result<Self, String>

Build config from env vars + CLI args. Removes AGENTMUX_AUTH_KEY from the environment after reading (matching Go behavior).

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
