Fields

target: Target

hardware: Hardware

layers: Vec<Layer>

2026-09-26: Own leaf, parent leaf, own common, parent common; the parent pair only when the tree inherits.

leaf: BTreeMap<String, Entry>

2026-09-26: Leaf-role files by name.

common: BTreeMap<String, Entry>

2026-09-26: Common-role files by name.

leaf_subdirs: BTreeMap<String, PathBuf>

2026-09-26: Subdirectories of the role directories (e.g. vendored headers), by name.

common_subdirs: BTreeMap<String, PathBuf>

shadows: Vec<Shadow>

source_model: String

2026-09-26: The model whose own-tier leaf directory this target reads, after redirect.

model_dir: PathBuf

2026-09-26: kernels/<hw>/<model>, the target’s own model directory.

Implementations

impl Layout

pub fn configs(&self) -> Vec<PathBuf>

2026-09-26: The KERNEL.tomls that exist, least specific first: parent common, own common, parent leaf, own leaf. The build script merges them in this order (build_resolve.rs).

pub fn modules(&self) -> Vec<(String, &Entry)>

2026-09-26: (stem, entry) for every module source, sorted by stem: leaf over common.

pub fn sources(&self) -> Vec<PathBuf>

2026-09-26: Module sources, sorted.

pub fn inputs(&self) -> BTreeSet<PathBuf>

2026-09-26: Every file the target’s compile reads through this resolution: the role entries, every file under the role subdirectories, and the KERNEL.tomls. The build script watches them for rebuilds (build_plan.rs).

pub fn role( &self, role: Role, ) -> (&BTreeMap<String, Entry>, &BTreeMap<String, PathBuf>)

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Layout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Layout

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

Formats the value using the given formatter.
