Struct BakedBootConfig 

#[repr(C)]
pub struct BakedBootConfig {
    pub magic: u32,
    pub version: u16,
    pub set_flags: u16,
    pub domain_id: u32,
    pub node_name: [u8; 64],
    pub locator: [u8; 96],
    pub namespace: [u8; 64],
    pub rmw: [u8; 32],
}

Build-time-baked boot config, emitted (in W4b) into the .nros_boot_config linker section by the entry macro / cmake. Fixed-size + pointer-free so a future post-link tool can patch it in place (RFC-0045). The resolver reads it on embedded via BootConfig::from_baked (in nros-node).

Fields

magic: u32

0x4E524243 = b“NRBC“. A post-link tool scans for this to locate the struct.

version: u16

Layout version (start at 1) — lets the tool/reader reject mismatched layouts.

set_flags: u16

One bit per field that is baked-set (else the reader yields None → resolver default). bit0 = node_name, bit1 = locator, bit2 = domain_id, bit3 = namespace, bit4 = rmw.

domain_id: u32

ROS 2 domain ID (valid only when BOOT_SET_DOMAIN bit is set).

node_name: [u8; 64]

NUL-padded UTF-8; the trailing NUL bytes are not part of the value.

locator: [u8; 96]

NUL-padded UTF-8 middleware locator; the trailing NUL bytes are not part of the value.

namespace: [u8; 64]

NUL-padded UTF-8 node namespace; the trailing NUL bytes are not part of the value.

rmw: [u8; 32]

Issue 1050 defect (3) — NUL-padded UTF-8 RMW backend selector (the name the registry is looked up by, e.g. "uorb"). Appended in layout version 2.

32 bytes because that is the registry’s own BACKEND_NAME_MAX; a longer name could never resolve, so accepting one here would only move the failure later.

Implementations

impl BakedBootConfig

pub const fn new( node_name: Option<&str>, locator: Option<&str>, domain_id: Option<u32>, namespace: Option<&str>, ) -> BakedBootConfig

Pack baked fields at compile time. None → field unset (bit clear, bytes zeroed). A string longer than its fixed buffer is a compile-time error (const panic) — never silently truncated.

must be const fn so W4b’s entry macro can use it in a static initializer.

pub const fn new_with_rmw( node_name: Option<&str>, locator: Option<&str>, domain_id: Option<u32>, namespace: Option<&str>, rmw: Option<&str>, ) -> BakedBootConfig

new plus the layout-version-2 rmw selector — issue 1050 defect (3).

Kept as a separate constructor rather than a fifth parameter on new because new is called from entry macros in board crates and from generated code; a signature change there is a break for every one of them, and this field is None at all but a handful of call sites.
