Struct WorkflowTemplate 

pub struct WorkflowTemplate {
    pub name: String,
    pub description: String,
    pub default_parameters: HashMap<String, Value>,
    /* private fields */
}

A named, reusable workflow configuration that can be instantiated into a WorkflowDag.

Fields

name: String

Unique template name.

description: String

Human-readable description.

default_parameters: HashMap<String, Value>

Default parameters shared by all nodes.

Implementations

impl WorkflowTemplate

pub fn new(name: impl Into<String>, description: impl Into<String>) -> Self

Create a new empty template.

pub fn with_default_parameter( self, key: impl Into<String>, value: Value, ) -> Self

Add a default parameter.

pub fn add_node( &mut self, task_type: impl Into<String>, parameters: HashMap<String, Value>, ) -> usize

Append a node spec; returns the spec index for use in add_edge.

pub fn add_edge( &mut self, from_idx: usize, to_idx: usize, data_type: impl Into<String>, )

Append an edge spec between two node indices.

pub fn instantiate( &self, overrides: &HashMap<String, Value>, ) -> Result<WorkflowDag, DagError>

Instantiate the template into a fresh WorkflowDag.

overrides can supply parameter overrides (merged with defaults).

pub fn node_count(&self) -> usize

Return the number of node specs.
