Struct WorkflowTemplate 

pub struct WorkflowTemplate {
    pub kind: WorkflowTemplateKind,
    pub name: String,
    pub description: String,
    pub steps: Vec<TemplateStep>,
    pub parameters: Vec<TemplateParameter>,
}

A pre-built workflow template for a common media processing pipeline.

Fields

kind: WorkflowTemplateKind

The kind of pipeline this template implements.

name: String

Human-readable name.

description: String

Longer description of what the pipeline does.

steps: Vec<TemplateStep>

Ordered list of steps (order determines DOT rendering; DAG edges come from depends_on).

parameters: Vec<TemplateParameter>

Parameters that can be tuned at instantiation time.

Implementations

impl WorkflowTemplate

pub fn new(kind: WorkflowTemplateKind) -> Self

Construct a fully-configured template for the given kind.

pub fn list_all() -> Vec<WorkflowTemplate>

Return one instance of each template kind.

pub fn instantiate( &self, params: &HashMap<String, String>, ) -> Result<WorkflowInstance, String>

Substitute {param_name} placeholders in step config values and return a WorkflowInstance.

Errors

Returns an error string when a required parameter is not present in params and has no default.

pub fn to_dot(&self) -> String

Generate a Graphviz DOT representation of the step dependency graph.
