Loops

Repeat agent actions until a condition is met

Loops let agents repeat actions until a goal is achieved.

Quick Start

1. Simple Loop

   use praisonai::r#loop;
   
   let workflow = r#loop(agent)
       .until(|result| result.contains("DONE"))
       .max_iterations(5);
   
   workflow.run("Keep improving until satisfied").await?;

2. With Counter

   use praisonai::r#loop;
   
   let workflow = r#loop(agent)
       .times(3);  // Run exactly 3 times
   
   workflow.run("Generate 3 ideas").await?;

How It Works

Configuration

Common Patterns

Refinement Loop

use praisonai::r#loop;

// Keep improving until quality is good
let workflow = r#loop(editor)
    .until(|result| quality_score(result) > 0.9)
    .max_iterations(5);

Retry Pattern

use praisonai::r#loop;

// Retry until success
let workflow = r#loop(api_caller)
    .until(|result| !result.contains("error"))
    .max_iterations(3);
