Implementations

impl RelationKind

pub const CORE: &'static [&'static str]

The core (non-extension) terms of this vocabulary.

pub fn as_str(&self) -> Cow<'_, str>

pub fn is_extension(&self) -> bool

impl RelationKind

pub fn meaning(&self) -> &'static str

Meaning of source --kind--> target.

pub fn target_kinds(&self) -> Option<&'static [RecordKind]>

Kinds the target must have, when the target is known locally.

pub fn requires_same_kind(&self) -> bool

Relations that only make sense between records of the same kind.

Trait Implementations

impl Clone for RelationKind

fn clone(&self) -> RelationKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RelationKind

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for RelationKind

impl Eq for RelationKind

impl FromStr for RelationKind

type Err = IdError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl Hash for RelationKind

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,

impl Ord for RelationKind

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for RelationKind

fn partial_cmp(&self, other: &RelationKind) -> 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
