pub struct PersonaManager { /* private fields */ }

Registry and runtime controller for AI personas.

Example

use tokio_prompt_orchestrator::persona_manager::{PersonaManager, default_personas};

let mut mgr = PersonaManager::default();
for p in default_personas() { mgr.register(p); }
assert!(mgr.activate("assistant"));
let persona = mgr.active_persona().unwrap();
let prompt = mgr.apply_persona("What is Rust?", persona);
assert!(prompt.contains("What is Rust?"));

Implementations

impl PersonaManager

pub fn register(&mut self, persona: Persona)

Register a new persona. If a persona with the same id already exists it is replaced.

pub fn activate(&mut self, id: &str) -> bool

Activate the persona with the given id.

Returns true if the persona was found and activated, false otherwise.

pub fn active_persona(&self) -> Option<&Persona>

Return a reference to the currently active persona, if any.

pub fn apply_persona(&self, prompt: &str, persona: &Persona) -> String

Build the final prompt string by prepending the system context and appending required disclaimers.

Format:

[SYSTEM]: <system_prompt>
[STYLE]: <style_notes>

<prompt>

<disclaimer_1>
<disclaimer_2>

pub fn validate_response( &self, response: &str, persona: &Persona, ) -> Vec<String>

Validate a model response against persona constraints.

Returns a list of human-readable violation messages (empty = valid).

pub fn blend_personas( &self, a_id: &str, b_id: &str, alpha: f64, ) -> Option<Persona>

Create a blended persona by interpolating the numeric constraints of persona a_id (weight alpha) and persona b_id (weight 1 - alpha).

The resulting persona’s system prompt is the concatenation of both system prompts separated by a newline. The voice of persona a is used. Returns None if either id is not found or alpha is outside [0, 1].

pub fn list_by_voice(&self, voice: &PersonaVoice) -> Vec<&Persona>

Return all personas that match the given voice.
