Struct Workflow 

pub struct Workflow {
    pub name: String,
    pub description: String,
    pub tools: IndexMap<String, ToolDef>,
    pub required_steps: Vec<String>,
    pub terminal_tools: HashSet<String>,
    pub system_prompt_template: String,
}

A validated workflow definition.

Fields

name: String

Name of the workflow.

description: String

Description of the workflow.

tools: IndexMap<String, ToolDef>

Map of tool names to their definition.

required_steps: Vec<String>

List of step names that must be completed.

terminal_tools: HashSet<String>

Set of tools designated as terminal (success terminates loop).

system_prompt_template: String

System prompt template containing variable interpolation placeholders.

Implementations

impl Workflow

pub fn new( name: impl Into<String>, description: impl Into<String>, tools: IndexMap<String, ToolDef>, required_steps: Vec<String>, terminal_tool: TerminalToolInput, system_prompt_template: impl Into<String>, ) -> Result<Self, String>

Construct and validate a Workflow.

Validates:

• Each tool dict key matches the tool definition’s name.
• Every required step exists in the tools map.
• Every terminal tool exists in the tools map.
• No terminal tool is also a required step.
• Every prerequisite references a tool that exists in the tools map.

pub fn build_system_prompt(&self, vars: &IndexMap<String, String>) -> String

Render the system prompt template with the provided variables.

pub fn get_tool_specs(&self) -> Vec<&ToolSpec>

Get all tool specs in insertion order.

pub fn get_callable(&self, tool_name: &str) -> Result<ToolCallable, String>

Get the callable for a tool by name.

Returns an error if the tool name is not found.

Trait Implementations

impl Debug for Workflow

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
