Struct Workspace 

pub struct Workspace {
    pub root: PathBuf,
    pub crates: BTreeMap<String, Vec<PathBuf>>,
    pub is_workspace_root: bool,
    pub standalone: BTreeMap<String, Vec<PathBuf>>,
}

The crates of a workspace: every Cargo.toml under root (skipping build and vcs dirs), keyed by both the package name and the [lib] name, - spelled _, mapped to the crate root files that claim the name — more than one when a facade package and the library it re-exports share it (aprender’s root aprender is pub use aprender_ml::* over crates/aprender-core, whose [lib] name is also aprender). The walk tries each in byte order of the manifest path and keeps the first that resolves.

Fields

root: PathBuf

crates: BTreeMap<String, Vec<PathBuf>>

is_workspace_root: bool

root/Cargo.toml has a [workspace] table. When it does, only its members (globs honoured) minus its exclude are crates — a stray manifest under the root (a test fixture, an excluded canary) is not a workspace member and a binding into it does not resolve (ONT-3a).

standalone: BTreeMap<String, Vec<PathBuf>>

Non-member manifests that declare their OWN [workspace] — a standalone cargo workspace under the root (experiments/cuda-oxide/gated-rmsnorm: its own toolchain and Cargo.lock). Indexed, NOT admitted: only a kernel: true binding naming one admits it (Workspace::admit_standalone, ONT-4c4).

Implementations

impl Workspace

pub fn scan(root: &Path) -> Self

Scan root for manifests. A manifest without a [package] name (a virtual workspace root) contributes nothing.

pub fn admit_standalone(&mut self, krate: &str) -> bool

Admit the standalone crate krate (a kernel: true binding names it) unless a member already owns the name. Returns whether anything was admitted.

Trait Implementations

impl Debug for Workspace

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

Formats the value using the given formatter.

impl Default for Workspace

fn default() -> Self

Returns the “default value” for a type.
