systemprompt-template-provider

Template provider traits for systemprompt.io AI governance infrastructure. Config-as-code foundation for the AI governance template registry. Includes an embedded loader for compile-time templates and a filesystem loader for runtime template discovery.

Layer: Shared — foundational types/traits with no dependencies on other layers. Part of the systemprompt-core workspace.

Overview

Provides template loading abstractions and dynamic type aliases for template-related providers. Includes an embedded loader for compile-time templates and a filesystem loader for runtime template discovery. Re-exports provider contracts for template, component, and page data handling.

Architecture

Type	Description
`TemplateLoader`	Trait for loading templates by name
`EmbeddedLoader`	Loader for compile-time embedded templates
`FileSystemLoader`	Async filesystem template loader (requires `tokio` feature)
`DynTemplateProvider`	`Arc<dyn TemplateProvider>` type alias
`DynTemplateLoader`	`Arc<dyn TemplateLoader>` type alias
`DynComponentRenderer`	`Arc<dyn ComponentRenderer>` type alias

Usage

[dependencies]
systemprompt-template-provider = "0.2.1"

use systemprompt_template_provider::{
    TemplateLoader, TemplateLoaderResult, EmbeddedLoader,
    DynTemplateProvider, DynTemplateLoader,
};
use async_trait::async_trait;

let loader: DynTemplateLoader = std::sync::Arc::new(EmbeddedLoader::new());

use std::sync::Arc;
use systemprompt_template_provider::{DynTemplateProvider, TemplateProvider};

fn register(provider: Arc<dyn TemplateProvider>) -> DynTemplateProvider {
    // Hand the provider to the runtime as a type-erased Arc.
    provider
}

Feature Flags

Feature	Default	Description
`tokio`	No	Enables `FileSystemLoader` for async file-based template loading

Dependencies
