Enum EntityType 

pub enum EntityType {
    Human,
    Enterprise,
    AiAgent,
    Programmable,
    Mask,
}

What kind of entity a ppnum is.

Members are exactly the storable values of scaccounts.ppnums.entity_type (ck_ppnums_entity_type_enum) — bound to that constraint by the enrollment directly below, so the constraint name lives on the fact.

There is no non_stored list, and that is the point: every member of this vocabulary is a real, storable entity kind. The render-only Delegated that the retired PAS enum had to declare as an exception is not an exception here — it is simply not an entity type. See the module docs.

The serde impls are feature-gated and off by default (PCS caches PpnumAccount as JSON in KVRocks and needs them; the only other consumer is PAS’s AdminLayer1 cache value, which carries a LifecycleState). The wire form is rename_all = "snake_case" — byte-identical to as_str, and not by coincidence: snake_case of each variant is the canonical string, so the derive cannot drift from TABLE. If a variant ever needs a form snake_case does not produce, delete the derive and write a manual impl that delegates to as_str — a second spelling of the wire strings is precisely the mirror this crate exists to remove.

Variants

Human

Natural person. Also the class of a token whose sub is a human being driven by an agent (ppnum lending) — the agent is act, not a different entity type.

Enterprise

Business or organization.

AiAgent

LLM-backed agent holding its own ppnum.

Programmable

Developer-programmable number (template / auto-reply). Infra class.

Mask

Ephemeral privacy-mediation proxy number with a TTL. Industry analogue: Twilio Masking Numbers / 안심번호.

Implementations

impl EntityType

pub const ALL: [EntityType; 5]

Every variant. Ordered as TABLE.

pub const fn index(self) -> usize

Stable position in ALL / TABLE.

The exhaustive match is the compile-time gate: a sixth variant fails to build here, so it cannot reach a claim by defaulting.

pub const fn facts(self) -> &'static EntityFacts

This variant’s row. Every attribute accessor below reads through it, so TABLE is the only place an attribute is stated.

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

Canonical wire/DB string.

pub const fn can_hold_credential(self) -> bool

May this entity hold a minted credential? See EntityFacts::can_hold_credential.

pub const fn requires_ai_disclosure(self) -> bool

Does this entity carry an AI-disclosure obligation? See EntityFacts::requires_ai_disclosure.

pub fn parse(s: &str) -> Option<EntityType>

Parse a canonical wire string. Exact inverse of as_str.

None for anything outside the vocabulary — notably "delegated", which is a session mode and never an entity type. Callers on a verify path MUST treat None as a forgery signal, not as an unknown-but-tolerable value.

Trait Implementations

impl Clone for EntityType

fn clone(&self) -> EntityType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EntityType

impl Debug for EntityType

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

Formats the value using the given formatter.

impl Display for EntityType

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

Formats the value using the given formatter.

impl Eq for EntityType

impl Hash for EntityType

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

where __H: Hasher,

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 Ord for EntityType

fn cmp(&self, other: &EntityType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for EntityType

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for EntityType

fn partial_cmp(&self, other: &EntityType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl SchemaConstrained for EntityType

const ALL: &'static [EntityType]

Every variant, in any order. The macro hand-lists these (no strum); the exhaustiveness guard makes an omission a build error and the DB test makes a stale list a pre-flight failure.

const CHECK_CONSTRAINTS: &'static [&'static str]

The CHECK constraint(s) whose IN (…) set must equal { ALL.map(db_value) }. More than one when several columns share the value-set (e.g. lifecycle_state on three columns).

fn db_value(&self) -> &'static str

The DB-text form of a variant — the literal stored in the column and named in the CHECK. Delegates to the enum’s inherent as_str / as_wire.

fn bindings() -> Vec<SchemaBinding>

Erased (constraint, allowed) pairs for the drift test — one per entry in CHECK_CONSTRAINTS.
