Struct TemplateRegistry 

pub struct TemplateRegistry { /* private fields */ }

Thread-safe registry of named prompt templates.

Cheap to clone (Arc-backed). The registry supports hot-reload: call register to add or replace a template at any time.

Implementations

impl TemplateRegistry

pub fn new() -> Self

pub fn register(&self, template: PromptTemplate)

Register (or replace) a template.

pub fn unregister(&self, name: &str)

Remove a template by name.

pub fn render( &self, name: &str, vars: &HashMap<&str, &str>, ) -> Result<String, TemplateError>

Render a named template with the supplied variables.

pub fn render_full( &self, name: &str, vars: &HashMap<&str, &str>, ) -> Result<(Option<String>, String), TemplateError>

Render a template and return (system_prompt, body).

pub fn get(&self, name: &str) -> Option<PromptTemplate>

Get a snapshot of a template (cloned).

pub fn names(&self) -> Vec<String>

List all registered template names.

pub fn load_toml(&self, toml_str: &str) -> Result<usize, String>

Load templates from a TOML string.

Expected format:

[[templates]]
name    = "summarise"
version = "v1"
system  = "You are a summariser."
body    = "Summarise: {{text}}"
tags    = ["nlp"]

[[templates]]
name = "translate"
body = "Translate to {{lang}}: {{text}}"
