Struct EdgeId 

pub struct EdgeId { /* private fields */ }

Collision-free identity for a stored edge or a synthesized reversal.

Generation zero is the original Helix edge. Positive generations identify synthesized reversals without modifying or reserving user-controlled IDs.

Implementations

impl EdgeId

pub fn original(id: impl Into<String>) -> EdgeId

Construct an original stored-edge identity.

pub fn synthesized_reverse( id: impl Into<String>, generation: u64, ) -> Option<EdgeId>

Construct a synthesized-reverse identity at a non-zero generation.

pub fn reversed(&self) -> Option<EdgeId>

Derive the next structural reversal when its generation is representable.

pub fn stored_id(&self) -> &str

Return the underlying stored Helix edge identity.

pub const fn reverse_generation(&self) -> u64

Zero for stored edges; positive for synthesized reversals.
