Struct CapabilitiesCfg 

pub struct CapabilitiesCfg(pub BTreeMap<String, bool>);

[capabilities] block: which optional subsystems a build of this app carries, keyed by capability name (os-tray, http-fetch, mcp, …).

Read by the builds that trim: lumenc package, which relinks the shared engine a folder package ships from the release’s engine kit, lumenc package --static, which replays a link kit into one executable, and lumenc bundle --static, which compiles a runtime from source and maps the names it knows to cargo features. An entry settles its capability outright; a capability the table leaves out follows its own rule against the app’s sources. A package that cannot relink its engine carries the full one and refuses a table that turns anything off. lumenc run carries everything and ignores the table. Script hosts come from the script files’ extensions (or [script] engine), not from here.

Implementations

impl CapabilitiesCfg

pub fn get(&self, name: &str) -> Option<bool>

pub fn set(&mut self, name: &str, on: bool)

Settle the capability called name.
