Struct RuntimeCfg 

Source 
pub struct RuntimeCfg {
    pub mcp: Option<bool>,
    pub hot_reload: Option<bool>,
    pub threads: Option<usize>,
}
Expand description

[runtime] block - per-app overrides for the startup subsystem-gating (measured startup quick-wins). Every field is Option: None keeps the automatic behaviour (run-mode gating for MCP / hot-reload; min(cores, 4) for threads), while Some(v) forces it.

[runtime]
mcp = false         # force the MCP server off (or true = on)
hot_reload = false  # force the source watcher off (or true = on)
threads = 2         # bevy_ecs worker-thread budget

Fields§

§mcp: Option<bool>

Force the MCP introspection server on/off. None = on for an interactive windowed run, off for a headless / bounded run (unless [mcp] simulate = true). Interacts with [mcp] port (a port = 0 still hard-disables).

§hot_reload: Option<bool>

Force the hot-reload source watcher on/off. None = on only for an interactive run from source (off for headless / bounded / artifact / in-memory).

§threads: Option<usize>

bevy_ecs worker-thread budget. None = min(available_parallelism, 4). Also overridable at runtime by the LUMEN_THREADS env var, which wins over this value.
