Struct EdgeAllocator 

pub struct EdgeAllocator { /* private fields */ }

Monotonic, per-object allocation of stable edge identities.

Removing an edge is deliberately not an allocator operation: allocated identities are evidence and remain consumed for the lifetime of their owner. Once the u32 identity space is exhausted, every later allocation fails without changing allocator state.

Implementations

impl EdgeAllocator

pub const fn new() -> Self

Creates an allocator whose first identity has ordinal zero.

pub fn allocate( &mut self, kind: EdgeKind, ) -> Result<TypedEdgeId, EdgeAllocationError>

Allocates the next identity with immutable kind semantics.
