Enum ProvRelationKind 

#[repr(u8)]
pub enum ProvRelationKind {
    None = 0,
    WasAttributedTo = 1,
    WasGeneratedBy = 2,
    WasDerivedFrom = 3,
    Used = 4,
    WasInformedBy = 5,
    WasAssociatedWith = 6,
    ActedOnBehalfOf = 7,
}

PROV-O relation kind (edge label).

None = 0 indicates an empty slot in ProvenanceHeader::relations. This makes the zero-value representation safe and lets arrays of relations be default-initialised cheaply.

Variants

None = 0

Empty slot - no relation.

WasAttributedTo = 1

Entity was attributed to Agent.

WasGeneratedBy = 2

Entity was generated by Activity.

WasDerivedFrom = 3

Entity was derived from another Entity.

Used = 4

Activity used an Entity.

WasInformedBy = 5

Activity was informed by another Activity.

WasAssociatedWith = 6

Activity was associated with an Agent.

ActedOnBehalfOf = 7

Agent acted on behalf of another Agent.

Implementations

impl ProvRelationKind

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

Try to parse from the wire u8 discriminant.

pub const fn as_u8(self) -> u8

Convert to the u8 discriminant.

pub const fn is_some(self) -> bool

Whether this slot carries a real relation (kind != None).

pub const fn expected_source_type(self) -> Option<ProvNodeType>

Expected PROV-O source node type for this relation’s subject.

Useful for type-check helpers before adding a relation to a builder.

Trait Implementations

impl Archive for ProvRelationKind

type Archived = ArchivedProvRelationKind

The archived representation of this type.

type Resolver = ProvRelationKindResolver

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: <Self as Archive>::Resolver, out: *mut <Self as Archive>::Archived, )

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

impl Clone for ProvRelationKind

fn clone(&self) -> ProvRelationKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProvRelationKind

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

Formats the value using the given formatter.

impl Default for ProvRelationKind

fn default() -> ProvRelationKind

Returns the “default value” for a type.

impl<__D: Fallible + ?Sized> Deserialize<ProvRelationKind, __D> for Archived<ProvRelationKind>

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

Deserializes using the given deserializer

impl Hash for ProvRelationKind

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<ArchivedProvRelationKind> for ProvRelationKind

fn eq(&self, other: &ArchivedProvRelationKind) -> 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<ProvRelationKind> for ArchivedProvRelationKind

fn eq(&self, other: &ProvRelationKind) -> 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 ProvRelationKind

fn eq(&self, other: &ProvRelationKind) -> 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: Fallible + ?Sized> Serialize<__S> for ProvRelationKind

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

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

impl Copy for ProvRelationKind
