Enum ProvNodeType 

#[repr(u8)]
pub enum ProvNodeType {
    Entity = 0,
    Activity = 1,
    Agent = 2,
    Plan = 3,
}

Classification of a PROV-O node.

Per the W3C PROV-O data model, a node is one of three top-level kinds (Entity, Activity, Agent). Plan is a Plan-subclass of Entity tracked explicitly so we can recognize audit programs without an extra lookup.

Variants

Entity = 0

A PROV Entity: data item, artifact, fact.

Activity = 1

A PROV Activity: computation, reasoning step, consolidation run.

Agent = 2

A PROV Agent: an auditor, an analytic, an LLM.

Plan = 3

A Plan (Entity subclass) - e.g. an audit program.

Implementations

impl ProvNodeType

pub const fn from_u8(value: u8) -> Option<ProvNodeType>

Try to parse from the wire u8 discriminant.

pub const fn as_u8(self) -> u8

Convert to the u8 discriminant.

pub const fn is_entity(self) -> bool

Whether this node is Entity-like (Entity or Plan).

Trait Implementations

impl Archive for ProvNodeType

type Archived = ArchivedProvNodeType

The archived representation of this type.

type Resolver = ProvNodeTypeResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: <ProvNodeType as Archive>::Resolver, out: *mut <ProvNodeType as Archive>::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for ProvNodeType

fn clone(&self) -> ProvNodeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProvNodeType

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

Formats the value using the given formatter.

impl<__D> Deserialize<ProvNodeType, __D> for <ProvNodeType as Archive>::Archived

where __D: Fallible + ?Sized,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<ProvNodeType, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Hash for ProvNodeType

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 PartialEq<ArchivedProvNodeType> for ProvNodeType

fn eq(&self, other: &ArchivedProvNodeType) -> 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.

impl PartialEq<ProvNodeType> for ArchivedProvNodeType

fn eq(&self, other: &ProvNodeType) -> 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.

impl PartialEq for ProvNodeType

fn eq(&self, other: &ProvNodeType) -> 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.

impl<__S> Serialize<__S> for ProvNodeType

where __S: Fallible + ?Sized,

fn serialize( &self, serializer: &mut __S, ) -> Result<<ProvNodeType as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Copy for ProvNodeType

impl Eq for ProvNodeType

impl StructuralPartialEq for ProvNodeType
