Crate tinyflows 

Core library surface for tinyflows — a Rust-native workflow engine.

tinyflows models an automation as a model::WorkflowGraph: a directed graph of typed model::Nodes connected by model::Edges. A compiler::compile step validates the graph and (from stage A1) lowers it onto the tinyagents state-graph engine, which the engine::run entry point drives.

The crate is deliberately host-agnostic: anything that touches the outside world — LLM calls, integration tools, HTTP, code execution, persistence — is expressed through the caps capability traits that the embedding application implements.

Modules

caps

Host-injected capability traits.

compiler

Compiles a WorkflowGraph into a runnable handle.

data

The runtime data model: the item-based currency that flows between nodes.

engine

Drives a CompiledWorkflow to completion by lowering it onto tinyagents.

error

Error types shared across validation, compilation, and execution.

expr

Expression evaluation for node config values (the =-prefix convention).

migrate

Load-time migration of persisted WorkflowGraph JSON.

model

The tinyflows workflow definition model: a directed graph of typed nodes.

nodes

Node execution: the NodeExecutor trait and per-kind implementations.

observability

Run/step observability records and the host-facing RunObserver hook.

validate

Structural validation for WorkflowGraphs, run before compilation.

Constants

The crate name published to crates.io.

Functions

product_name
