Trait ToPromptSet

Source

pub trait ToPromptSet {
    // Required method
    fn to_prompt_parts_for(
        &self,
        target: &str,
    ) -> Result<Vec<PromptPart>, PromptSetError>;

    // Provided method
    fn to_prompt_for(&self, target: &str) -> Result<String, PromptSetError> { ... }
}

Expand description

A trait for types that can generate multiple named prompt targets.

This trait enables a single data structure to produce different prompt formats for various use cases (e.g., human-readable vs. machine-parsable formats).

§Example

use llm_toolkit::prompt::{ToPromptSet, PromptPart};
use serde::Serialize;

#[derive(ToPromptSet, Serialize)]
#[prompt_for(name = "Visual", template = "## {{title}}\n\n> {{description}}")]
struct Task {
    title: String,
    description: String,

    #[prompt_for(name = "Agent")]
    priority: u8,

    #[prompt_for(name = "Agent", rename = "internal_id")]
    id: u64,

    #[prompt_for(skip)]
    is_dirty: bool,
}

let task = Task {
    title: "Implement feature".to_string(),
    description: "Add new functionality".to_string(),
    priority: 1,
    id: 42,
    is_dirty: false,
};

// Generate visual prompt
let visual_prompt = task.to_prompt_for("Visual")?;

// Generate agent prompt
let agent_prompt = task.to_prompt_for("Agent")?;
