AshAi extension guidelines for integrating AI capabilities with Ash Framework. Use when implementing vectorization/embeddings, exposing Ash actions as LLM tools, creating prompt-backed actions, or setting up MCP servers. Covers semantic search, LangChain integration, and structured outputs.
This skill should be used when solving hard questions, complex architectural problems, or debugging issues that benefit from GPT-5 Pro or GPT-5.1 thinking models with large file context. Use when standard Claude analysis needs deeper reasoning or extended context windows.

Quick Reference (30 seconds)
Rust 1.92+ Development Specialist with deep patterns for high-performance, memory-safe applications.
Auto-Triggers: .rs, Cargo.toml, async/await, Tokio, Axum, SQLx, serde, lifetimes, traits
Core Use Cases:
High-performance REST APIs and microservices
Memory-safe concurrent systems
CLI tools and system utilities
WebAssembly applications
Low-latency networking services
Quick Patterns:
Axum REST API:
let app = Router::new ()
.route ("/api/users/:id" , get (get_user))
.with_state (app_state);
let listener = tokio::net::TcpListener::bind ("0.0.0.0:3000" ).await ?;
axum::serve (listener, app).await ?;
Async Handler with SQLx:
async fn get_user (
State (state): State<AppState>,
Path (id): Path<i64 >,
) -> Result <Json<User>, AppError> {
let user = sqlx::query_as!(User, "SELECT * FROM users WHERE id = $1" , id)
.fetch_optional (&state.db).await ?
.ok_or (AppError::NotFound)?;
Ok (Json (user))
}

Rust 1.92 Features
Modern Rust Features:
Rust 2024 Edition available (released with Rust 1.85)
Async traits in stable (no more async-trait crate needed)
Const generics for compile-time array sizing
let-else for pattern matching with early return
Improved borrow checker with polonius trait AsyncRepository {
async fn get (&self , id: i64 ) -> Result <User, Error>;
async fn create (&self , user: CreateUser) -> Result <User, Error>;
}
impl AsyncRepository for PostgresRepository {
async fn get (&self , id: i64 ) -> Result <User, Error> {
sqlx::query_as!(User, "SELECT * FROM users WHERE id = $1" , id)
.fetch_one (&self .pool).await
}
}
fn get_user (id: Option <i64 >) -> Result <User, Error> {
let Some (id) = id else { return Err (Error::MissingId); };
let Ok (user) = repository.find (id) else { return Err (Error::NotFound); };
Ok (user)
}
Web Framework: Axum 0.8 [dependencies]
axum = "0.8"
tokio = { version = "1.48" , features = ["full" ] }
tower-http = { version = "0.6" , features = ["cors" , "trace" ] }
use axum::{extract::{Path, State, Query}, routing::{get, post}, Router, Json};
use tower_http::cors::CorsLayer;
#[derive(Clone)]
struct AppState { db: PgPool }
#[tokio::main]
async fn main () -> Result <(), Box <dyn std::error::Error>> {
let pool = PgPoolOptions::new ()
.max_connections (25 )
.connect (&std::env::var ("DATABASE_URL" )?).await ?;
let app = Router::new ()
.route ("/api/v1/users" , get (list_users).post (create_user))
.route ("/api/v1/users/:id" , get (get_user))
.layer (CorsLayer::permissive ())
.with_state (AppState { db: pool });
let listener = tokio::net::TcpListener::bind ("0.0.0.0:3000" ).await ?;
axum::serve (listener, app).await ?;
Ok (())
}
async fn list_users (
State (state): State<AppState>,
Query (params): Query<ListParams>,
) -> Result <Json<Vec <User>>, AppError> {
let users = sqlx::query_as!(User,
"SELECT * FROM users ORDER BY created_at DESC LIMIT $1 OFFSET $2" ,
params.limit.unwrap_or (10 ), params.offset.unwrap_or (0 ))
.fetch_all (&state.db).await ?;
Ok (Json (users))
}
Async Runtime: Tokio 1.48 Task Spawning and Channels:
use tokio::sync::mpsc;
async fn worker_pool () {
let (tx, mut rx) = mpsc::channel::<Job>(100 );
for _ in 0 ..4 {
tokio::spawn (async move {
while let Some (job) = rx.recv ().await { process_job (job).await ; }
});
}
}
async fn timeout_operation () -> Result <Data, Error> {
tokio::select! {
result = fetch_data () => result,
_ = tokio::time::sleep (Duration::from_secs (5 )) => Err (Error::Timeout),
}
}
Database: SQLx 0.8 #[derive(Debug, sqlx::FromRow)]
struct User { id: i64 , name: String , email: String }
async fn user_operations (pool: &PgPool) -> Result <(), sqlx::Error> {
let user = sqlx::query_as!(User,
"SELECT id, name, email FROM users WHERE id = $1" , 1i64 )
.fetch_one (pool).await ?;
let mut tx = pool.begin ().await ?;
sqlx::query!("INSERT INTO users (name, email) VALUES ($1, $2)" , "John" , "john@example.com" )
.execute (&mut *tx).await ?;
tx.commit ().await ?;
Ok (())
}
Serialization: Serde 1.0 use serde::{Deserialize, Serialize};
#[derive(Debug, Serialize, Deserialize)]
#[serde(rename_all = "camelCase" )]
struct User {
id: i64 ,
#[serde(rename = "userName" )]
name: String ,
#[serde(skip_serializing_if = "Option::is_none" )]
profile_url: Option <String >,
#[serde(default)]
is_active: bool ,
}
Error Handling use thiserror::Error;
#[derive(Error, Debug)]
pub enum AppError {
#[error("database error: {0}" )]
Database (#[from] sqlx::Error),
#[error("not found: {0}" )]
NotFound (String ),
#[error("unauthorized" )]
Unauthorized,
}
impl IntoResponse for AppError {
fn into_response (self ) -> Response {
let (status, message) = match &self {
AppError::NotFound (_) => (StatusCode::NOT_FOUND, self .to_string ()),
AppError::Unauthorized => (StatusCode::UNAUTHORIZED, self .to_string ()),
AppError::Database (_) => (StatusCode::INTERNAL_SERVER_ERROR, "Internal error" .into ()),
};
(status, Json (json!({"error" : message}))).into_response ()
}
}
CLI Development: clap use clap::{Parser, Subcommand};
#[derive(Parser)]
#[command(name = "myapp" , version, about)]
struct Cli {
#[arg(short, long, global = true)]
config: Option <PathBuf>,
#[command(subcommand)]
command: Commands,
}
#[derive(Subcommand)]
enum Commands {
Serve { #[arg(short, long, default_value = "3000" )] port: u16 },
Migrate,
}
fn main () {
let cli = Cli::parse ();
match cli.command {
Commands::Serve { port } => serve (port),
Commands::Migrate => migrate (),
}
}
Testing Patterns #[cfg(test)]
mod tests {
use super::*;
#[tokio::test]
async fn test_create_user () {
let pool = setup_test_db ().await ;
let result = create_user (&pool, "John" , "john@example.com" ).await ;
assert! (result.is_ok ());
assert_eq! (result.unwrap ().name, "John" );
}
}
