Parsed lumen.toml config, all fields optional.

Fields

raw: Table

The whole file, parsed but untyped. What an optional subsystem reads its own section from: the typed fields above are the runtime’s, and a subsystem the runtime does not name has no field here.

app: AppCfg

[app] section.

pages: PagesCfg

[pages] section - file-based multi-page navigation config.

window: WindowCfg

[window] section.

skin: SkinCfg

[skin] section.

mcp: McpCfg

[mcp] section.

profile: ProfileCfg

[profile] section.

asset_roots: AssetRootsCfg

[asset_roots] section.

script: ScriptCfg

[script] section - script-engine selection.

render: RenderCfg

[render] section - which render backend draws the app.

perf: PerfCfg

[perf] section - per-cache memory budgets.

runtime: RuntimeCfg

[runtime] section - subsystem init overrides (MCP / hot-reload / thread budget).

capabilities: CapabilitiesCfg

[capabilities] section - per-app COMPILE-TIME subsystem trim toggles for the static --bundle build (Part B tree-shaking).

web: WebCfg

[web] section - how lumenc web emits the app as a static site.

hooks: Vec<HookCfg>

[[hooks]] array - project-declared build/setup commands, run at the prebuild / prerun trigger points by lumenc run / build / bundle. See crate::hooks for the execution semantics (ordering, OS filtering, staleness skip) and HookCfg for the field reference.

plugins: Vec<Value>

[[plugins]] array - compiler plugins, run in declaration order by every compile path, check included. This field only accepts the array (deny_unknown_fields would otherwise reject any app declaring one); nothing reads it. The schema, the loader, and the validation live in lumenc-plugin (see its PluginCfg), lumenc reads the file itself, and the chain reaches the pipeline through the injected crate::compiler_plugins::CompilerPlugins boundary, the same inversion the parser uses.

dependencies: DependenciesCfg

[dependencies] table - prebuilt dylibs loaded at startup in sorted-name order: engine-linked runtime modules and portable C-ABI plugins, told apart by their exports. The schema, the loader, and the failure policy live in lumen-modules (re-exported as crate::modules); build_app runs the table through the loader when the modules feature is on.

target: TargetTables

[target.web] and [target.desktop]: what a build for one target adds. Each may carry a dependencies table of the same shape as [dependencies], laid over it for that target’s builds; read the combined table through Self::dependencies_for.

signals: SignalsCfg

[signals] table - optional typed schema. Each key declares the expected SignalType. Used by lumenc lint --signals to flag untyped writes / schema mismatches. Schema entries are optional: missing keys just downgrade the lint severity.

Implementations

impl LumenToml

pub fn load_or_default(dir: &Path) -> Result<Self, ConfigError>

Loads <dir>/lumen.toml when present and returns the parsed config; returns Self::default when the file is absent.

pub fn dependencies_for(&self, target: Target) -> DependenciesCfg

The dependencies a build for target takes: [dependencies], with [target.<name>.dependencies] laid over it entry by entry.

pub fn resolved_asset_roots(&self, dir: &Path) -> Vec<PathBuf>

Returns [asset_roots].paths resolved against dir, leaving absolute entries unchanged and joining relative entries onto dir.

Trait Implementations

impl Clone for LumenToml

fn clone(&self) -> LumenToml

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LumenToml

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

Formats the value using the given formatter.

impl Default for LumenToml

fn default() -> LumenToml

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LumenToml

where LumenToml: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
