Struct GraphBuilder 

pub struct GraphBuilder { /* private fields */ }

Mutable scratch state for assembling a dynamic graph inside a GraphDsl closure.

Tracks registered stages, their ports, the edges wired between them, and any deferred wiring errors (raised by wire, which collects rather than short-circuits). finish consumes it into a validated GraphBlueprint. Use this builder for cycles, runtime-data-dependent topology, erased interop, connect_any, and method-based wire construction. For static typed graphs where double-wiring should be rejected by Rust moves, use TypedGraphBuilder.

Implementations

impl GraphBuilder

pub fn add<G: GraphStage>(&mut self, stage: G) -> G::Shape

pub fn add_with_attributes<G: GraphStage>( &mut self, stage: G, attributes: Attributes, ) -> G::Shape

pub fn add_named<G: GraphStage>( &mut self, stage: G, name: impl Into<String>, ) -> G::Shape

pub fn connect<T: 'static>( &mut self, outlet: Outlet<T>, inlet: Inlet<T>, ) -> StreamResult<()>

pub fn connect_any( &mut self, outlet: AnyOutlet, inlet: AnyInlet, ) -> StreamResult<()>

Connect type-erased ports for dynamic graph construction and interop.

This remains an explicit compatibility surface for cases where the element type is only known at runtime. Prefer connect or TypedGraphBuilder for static Rust graphs.

pub fn import<S: Shape>(&mut self, graph: &PartialGraph<S>) -> StreamResult<S>

pub fn wire<W: WireSpec>(&mut self, spec: W) -> &mut Self

Apply a dynamic/method-based wiring spec, deferring errors to finish.

wire is useful for graph DSL ergonomics and interop-style topology construction. Static Rust graphs can use TypedGraphBuilder when compile-time double-wire rejection is desired.

pub fn try_wire<W: WireSpec>(&mut self, spec: W) -> StreamResult<&mut Self>

Apply a dynamic/method-based wiring spec, returning wiring errors immediately.

This is the fallible counterpart to wire and remains a runtime-validated dynamic/interop surface.
