Enum BcsrRole 

pub enum BcsrRole {
    Head,
    Tail,
}

Side of a directed hyperedge an incidence belongs to.

oxgraph-hyper keeps the participation role as an associated type rather than a concrete enum so views can pick whatever vocabulary fits their storage. BcsrRole is the role chosen for BcsrHypergraph: each participant is either on the head side or the tail side of a directed hyperedge. Role bytes are not stored — the role is recovered from which section the participant lives in.

Performance

Copying, comparing, ordering, hashing, and debug-formatting are O(1).

Variants

Head

The vertex participates on the source (head) side of a directed hyperedge.

Tail

The vertex participates on the target (tail) side of a directed hyperedge.

Trait Implementations

impl Clone for BcsrRole

fn clone(&self) -> BcsrRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BcsrRole

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

Formats the value using the given formatter.

impl Hash for BcsrRole

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 Ord for BcsrRole

fn cmp(&self, other: &BcsrRole) -> 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.

impl PartialEq for BcsrRole

fn eq(&self, other: &BcsrRole) -> 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 PartialOrd for BcsrRole

fn partial_cmp(&self, other: &BcsrRole) -> 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.
