Struct Edge 

pub struct Edge { /* private fields */ }

Fluent builder for a single edge declaration.

Implementations

impl Edge

pub fn new(idx: usize) -> Self

Start an edge builder for edge index idx.

The index is the stable edge identifier used in descriptors. It must be unique among real (non-ingress) edges.

pub fn ty<T: 'static>(self) -> Self

Set the edge queue type using a real Rust type T.

pub fn payload<T: 'static>(self) -> Self

Set the edge payload type using a Rust type T.

pub fn manager_ty<M: 'static>(self) -> Self

Set the memory manager type for this edge using a real Rust type M.

Every edge must specify a manager type. For no_std graphs, use StaticMemoryManager<P, DEPTH> where DEPTH matches the queue’s max_items. For std concurrent graphs, use ConcurrentMemoryManager<P>.

pub fn from(self, node: usize, port: usize) -> Self

Set the upstream (node_index, port_index) for this edge.

pub fn to(self, node: usize, port: usize) -> Self

Set the downstream (node_index, port_index) for this edge.

pub fn policy(self, p: EdgePolicy) -> Self

Supply a concrete EdgePolicy value (converted internally).

pub fn name(self, s: Option<&'static str>) -> Self

Set the optional edge name using a Rust &'static str (or None).
