Struct DeployOverlay 

pub struct DeployOverlay {
    pub locator: Option<&'static str>,
    pub ip: Option<[u8; 4]>,
    pub gateway: Option<[u8; 4]>,
    pub netmask: Option<[u8; 4]>,
    pub domain_id: Option<u32>,
    pub transport: Option<&'static str>,
}

Deploy-metadata overlay threaded from nros::main!() into the board’s boot config (issue #48 cause 1).

The nros::main!() macro reads the Entry pkg’s [package.metadata.nros.deploy.<board>] block at expansion time and bakes the present keys here. Each field is None when the deploy block omitted it, so the board overlays only the supplied values onto its own Config::default() (the firmware’s compiled-in default stays the source of truth for everything the deploy block does not name).

Boards whose BoardEntry::run ignores network/locator config (POSIX hosts, RTIC/Embassy MCUs that take their transport elsewhere) inherit the default BoardEntry::run_with_deploy body, which drops the overlay and calls BoardEntry::run — so adding fields here never touches those boards.

Fields

locator: Option<&'static str>

locator = "tcp/10.0.2.2:7451" — the zenoh/RMW endpoint the firmware dials. None → keep the board default.

ip: Option<[u8; 4]>

ip = "10.0.2.15" — static guest IP. None → keep the board default.

gateway: Option<[u8; 4]>

gateway = "10.0.2.2" — default route. None → keep the board default.

netmask: Option<[u8; 4]>

netmask = "255.255.255.0". None → keep the board default.

domain_id: Option<u32>

domain_id = 0 — ROS 2 domain. None → keep the board default.

transport: Option<&'static str>

transport = "xrce" — select a board custom transport that must be installed BEFORE the linked RMW registers (e.g. an XRCE-over-UART vtable). None → the board’s default transport. Honored by BoardEntry::setup_transport (phase-244.D1).
