Enum EntityKind 

pub enum EntityKind {
    Concept,
    Document,
    Dataset,
    Project,
    Person,
    Org,
    Artifact,
    Service,
}

8 closed base kinds for graph-node classification.

Governed subtype values live in Entity::entity_type; properties remain metadata and must not carry ontology type strings.

Variants

Concept

Algorithms, techniques, architectures, theories, models, research gaps. The default / residual bucket.

Document

Papers, preprints, technical reports, blog posts, books. Has: title, authors, year, venue, DOI/URL.

Dataset

Benchmarks, corpora, evaluation sets. Has: task type, size, metrics, license.

Project

Codebases, libraries, tools, frameworks. Has: language, repo URL, license.

Person

Researchers, engineers, authors.

Org

Labs, companies, institutions.

Artifact

Built artifacts: binaries, model checkpoints, Docker images, packages.

Service

Running or deployable services: APIs, hosted endpoints, SaaS products.

Implementations

impl EntityKind

pub const ALL: [Self; 8]

All 8 canonical entity kinds in taxonomy-table order.

pub const fn name(self) -> &'static str

Return the canonical lowercase string for this kind, as stored on the wire.

Trait Implementations

impl Clone for EntityKind

fn clone(&self) -> EntityKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EntityKind

impl Debug for EntityKind

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

Formats the value using the given formatter.

impl Default for EntityKind

fn default() -> EntityKind

Returns the “default value” for a type.

impl Display for EntityKind

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

Formats the value using the given formatter.

impl Eq for EntityKind

impl FromStr for EntityKind

fn from_str(s: &str) -> Result<Self, Self::Err>

Parse a string into an EntityKind.

Accepts the 8 canonical kind names (case-insensitive) plus a set of convenience aliases to aid human-authored DSL requests (e.g. "paper" resolves to Document, "repo" to Project).

Note on subtype aliasing: when kind="paper" is parsed here, only the base EntityKind::Document is returned. Callers that need to preserve the entity_type subtoken must use the pack registry resolution path, which returns both the base kind and the subtype string. from_str is intentionally base-kind-only for use in contexts where the subtype is carried separately (e.g. Entity.entity_type).

type Err = UnknownVariant

The associated error which can be returned from parsing.

impl Hash for EntityKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EntityKind

fn eq(&self, other: &EntityKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
