Module template 

Prompt Template Engine

Simple {{variable}} substitution engine with filter support.

Variable Syntax

• {{var}} — plain substitution.
• {{var | upper}} — apply the upper filter.
• {{var | lower}} — apply the lower filter.
• {{var | truncate:100}} — truncate to 100 characters.
• {{var | default:"fallback"}} — use "fallback" if var is missing.

Example

use tokio_prompt_orchestrator::template::{
    PromptTemplate, TemplateContext, TemplateValue,
};

let t = PromptTemplate::from_str("Hello, {{name | upper}}!").unwrap();
let mut ctx = TemplateContext::new();
ctx.set("name", TemplateValue::Text("world".to_string()));
let rendered = t.render(&ctx).unwrap();
assert_eq!(rendered, "Hello, WORLD!");
