Enum terminus_store::layer::ObjectType

pub enum ObjectType {
    Node(String),
    Value(String),
}

The type of an object in a triple.

Objects in a triple may either be a node or a value. Nodes can be used both in the subject and the object position, while values are only used in the object position.

Terminus-store keeps track of whether an object was stored as a node or a value, and will return this information in queries. It is possible to have the same string appear both as a node and a value, without this leading to conflicts.

Variants

Node(String)

Value(String)

Trait Implementations

impl Clone for ObjectType

fn clone(&self) -> ObjectType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectType

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

Formats the value using the given formatter.

impl Eq for ObjectType

impl Hash for ObjectType

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for ObjectType

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

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<ObjectType> for ObjectType

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<ObjectType> for ObjectType

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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