Struct Node 

pub struct Node { /* private fields */ }

Fluent builder for a single node declaration.

Implementations

impl Node

pub fn new(idx: usize) -> Self

Start a node builder for node index idx.

The index is the stable node identifier used throughout the generated graph. It must be unique within the graph.

Examples

use limen_codegen::builder::Node;
let n = Node::new(0);

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

Set the concrete node type using a real Rust type T. This avoids calling syn::parse_quote! at the call site.

pub fn in_ports(self, n: usize) -> Self

Set the number of input ports for this node.

If in_ports == 0 and out_ports > 0, the node will be treated as a source by codegen.

pub fn out_ports(self, n: usize) -> Self

Set the number of output ports for this node.

If out_ports == 0 and in_ports > 0, the node will be treated as a sink by codegen.

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

Set the input payload type using a Rust type T.

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

Set the output payload type using a Rust type T.

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

Set the optional node name from a Rust &'static str (or None).

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

Supply a concrete EdgePolicy value for ingress policy (converted internally).
