Struct Link 

#[repr(C)]
pub struct Link<T: LinkReference> {
    pub index: T,
    pub source: T,
    pub target: T,
}

A link triple (index, source, target) that represents one node in the doublets graph.

Every link is uniquely identified by its index and connects a source to a target.

Fields

index: T

Unique identifier of this link within the store.

source: T

The source (left) endpoint of this link.

target: T

The target (right) endpoint of this link.

Implementations

impl<T: LinkReference> Link<T>

pub fn nothing() -> Self

Returns a default/null link with all fields set to zero.

pub const fn new(index: T, source: T, target: T) -> Self

Creates a new link with the given index, source, and target.

pub const fn point(val: T) -> Self

Creates a self-referential (point) link where index == source == target.

pub const fn from_slice(slice: &[T]) -> Self

Constructs a Link from the first three elements of slice.

Panics

Panics if slice.len() < 3.

pub fn is_null(&self) -> bool

Returns true if this is the null (zero) link.

pub fn is_full(&self) -> bool

Returns true if the link is a full point (index == source == target).

pub fn is_partial(&self) -> bool

Returns true if index equals either source or target.

pub const fn as_slice(&self) -> &[T]

Returns the link fields as a three-element slice [index, source, target].
