Module node

Module node 

Source
Expand description

Public Node + lazy build chain. Node — the framework’s runtime construct, installed via [bytesandbrains::install] and driven through Node::poll.

Lifecycle:

let model    = MyModule.build()?;
let compiled = bb::Compiler::new()
    .bind_backend::<CpuBackend>("compute")
    .compile(model)?;
let mut node = bb::install(peer_id, addr, compiled, &["MyModule"], bb::Config::new())?;
loop { node.poll(&mut cx); }

Construction-time validation (passport check, binding-table parse, concrete construction) surfaces InstallError at install time — the engine is ready to dispatch by the time Node::poll sees it.

Modules§

config
Construction-time configuration for a Node.
derivation
Free fns that derive compiler-friendly summaries off a bare ModelProto. The chosen-path install constructs concrete instances via the inventory’s construct_fn at install time; the IR carries no instance state, so the only derivations the compiler + Node need are the generic-placeholder slot specs and the partition name.

Structs§

Node
Constructed BB Node ready to drive ML work. Produced by [bytesandbrains::install] — by the time the host holds one, the engine has resolved its dispatch table, registered every bound concrete, and installed the target function as the root graph.

Enums§

BootstrapTarget
Selector for Node::run_bootstrap. One enum, four variants covering every bootstrap-kick shape — install-order, by Module target name, by Module target name with staged inputs, and by Component slot.

Type Aliases§

TelemetryTap
Type-erased EngineStep observer installed onto a Node via Node::set_telemetry_tap. Each Node::poll call invokes the closure once per produced step.
