AllFrame

The Composable Rust API Framework

One frame to rule them all. Transform, compose, ignite.

What is AllFrame?

AllFrame is the first Rust web framework designed, built, and evolved exclusively through Test-Driven Development (TDD). Every feature, macro, and public API has a failing test before it is written.

We ship composable crates that give you exactly what you need, with zero external runtime dependencies:

// Configure gRPC Explorer with all features
let config = GrpcExplorerConfig::new()
    .server_url("http://localhost:50051")
    .enable_reflection(true)      // Auto-discover services
    .enable_tls(false)             // TLS for production

✅ Contract Testing

use allframe::router::{Router, ContractTester, ContractTestConfig};

let router = Router::new();

// Simple usage - test all routes
let results = router.generate_contract_tests();
assert!(results.all_passed());
println!("Coverage: {:.1}%", results.coverage);

// Advanced usage with configuration
let tester = ContractTester::with_config(
    &router,
    ContractTestConfig::new()
        .validate_requests(true)
        .validate_responses(true)
        .detect_breaking_changes(true)
        .fail_fast(false)
);

let results = tester.test_all_routes();
println!("Passed: {}/{}", results.passed, results.total);

// Test specific route
let result = router.test_route_contract("/users", "GET");
assert!(result.passed);

Features:

✅ Automatic test generation from router
📋 Schema validation (requests/responses)
🔍 Breaking change detection
📊 Coverage reporting
🎯 Test specific routes or all at once

🔄 Protocol-Agnostic Handlers

#[handler(protocols = ["rest", "graphql", "grpc"])]
async fn create_user(input: CreateUserInput) -> Result<User, Error> {
    // Same handler works as:
    // - POST /users (REST)
    // - mutation { createUser } (GraphQL)
    // - CreateUser(request) (gRPC)
}

🏛️ CQRS + Event Sourcing (85% Less Boilerplate!)

use allframe::prelude::*;

// Commands - 90% reduction (3 lines vs 30-40)
#[command_handler]
async fn create_user(cmd: CreateUserCommand) -> CommandResult<UserEvent> {
    Ok(vec![UserEvent::Created { user_id: cmd.user_id, email: cmd.email }])
}

// Projections - 90% reduction (5 lines vs 50+)
let registry = ProjectionRegistry::new(event_store);
registry.register("users", UserProjection::new()).await;
registry.rebuild("users").await?;

// Event Versioning - 95% reduction (5 lines vs 30-40)
registry.register_upcaster(AutoUpcaster::<V1, V2>::new()).await;
// Events automatically upcasted during replay!

// Sagas - 75% reduction (20 lines vs 100+)
let saga = SagaDefinition::new("transfer")
    .add_step(DebitStep { account: from, amount })
    .add_step(CreditStep { account: to, amount });
orchestrator.execute(saga).await?;
// Automatic compensation on failure!

🤖 MCP Server (LLM Tool Calling)

Expose your AllFrame APIs as LLM-callable tools using the Model Context Protocol.

Installation:

# Opt-in to MCP server (zero overhead if not used!)
[dependencies]
allframe-core = "0.1"
allframe-mcp = "0.1"  # Separate crate - 100% zero bloat!
tokio = { version = "1.48", features = ["full"] }

Quick Start:

use allframe_core::router::Router;
use allframe_mcp::McpServer;

#[tokio::main]
async fn main() {
    // Create router with handlers
    let mut router = Router::new();
    router.register("get_user", |user_id: String| async move {
        format!("User: {}", user_id)
    });
    router.register("create_order", |product: String| async move {
        format!("Order created for: {}", product)
    });

    // Handlers automatically become LLM-callable tools!
    let mcp = McpServer::new(router);

    // List available tools
    let tools = mcp.list_tools().await;
    println!("Available tools: {}", tools.len());

    // Call a tool
    let result = mcp.call_tool(
        "get_user",
        serde_json::json!({"user_id": "123"})
    ).await;
}

Features:

✅ Auto-discovery: Every handler becomes an MCP tool
✅ JSON Schema generation and validation
✅ Type coercion (string → number, boolean)
✅ 100% zero overhead when not used (opt-in only)
✅ Flexible deployment (standalone, embedded, serverless)

Usage Patterns:

📱 Standalone MCP server binary for Claude Desktop
🌐 Embedded in web applications (Axum, Actix, Rocket)
☁️ Serverless deployment (AWS Lambda, etc.)

cargo run

OpenAPI docs automatically available at:

http://localhost:8080/swagger-ui
http://localhost:8080/openapi.json

Feature Flags

AllFrame uses Cargo feature flags to minimize bloat - you only pay for what you use:

[dependencies]
allframe-core = { version = "0.1", features = ["di", "openapi"] }

Core Features

Feature	Description	Binary Impact	Default
`di`	Compile-time dependency injection	+0KB	✅
`openapi`	Auto OpenAPI 3.1 + Swagger UI	+0KB	✅
`router`	Protocol-agnostic routing + TOML config	+50KB	✅

Router Features (Protocol Support)

Feature	Description	Binary Impact	Default
`router-graphql`	Production GraphQL (async-graphql, GraphiQL)	+2MB	❌
`router-grpc`	Production gRPC (tonic, streaming, reflection)	+3MB	❌
`router-full`	Both GraphQL + gRPC production adapters	+5MB	❌

CQRS Features (✅ Complete - Phases 1-5)

Feature	Description	Reduction	Default
`cqrs`	CQRS + Event Sourcing infrastructure	85% avg	✅
`cqrs-allsource`	AllSource backend (embedded DB)	-	❌
`cqrs-postgres`	PostgreSQL backend (planned)	-	❌
`cqrs-rocksdb`	RocksDB backend (planned)	-	❌

What you get:

CommandBus with automatic validation (90% reduction)
ProjectionRegistry with automatic lifecycle (90% reduction)
Event Versioning with auto-upcasting (95% reduction)
Saga Orchestration with automatic compensation (75% reduction)
Pluggable backends (in-memory, AllSource, custom)

MCP Server (Separate Crate)

MCP (Model Context Protocol) is now a separate crate for 100% zero bloat:

# Only add if you need LLM integration
[dependencies]
allframe-mcp = "0.1"

Benefits:

✅ 100% zero overhead when not used
✅ No feature flags needed
✅ No compilation impact on core
✅ Independent versioning

See MCP Zero-Bloat Strategy for details.

💡 Tip: Start minimal and add features as needed. See docs/feature-flags.md for detailed guidance.

Examples

Minimal REST API:

allframe-core = { version = "0.1", default-features = false, features = ["router"] }

Production GraphQL API:

allframe-core = { version = "0.1", features = ["router-graphql"] }

Multi-Protocol Gateway:

allframe-core = { version = "0.1", features = ["router-full"] }

Philosophy

Test-Driven Development (TDD)

We do not write a single line of implementation until a test fails for it.

// 1. RED - Write failing test
#[test]
fn test_user_creation() {
    let user = User::new("test@example.com");
    assert!(user.is_ok());
}

// 2. GREEN - Minimal implementation
pub struct User { email: String }
impl User {
    pub fn new(email: impl Into<String>) -> Result<Self, Error> {
        Ok(Self { email: email.into() })
    }
}

// 3. REFACTOR - Improve while keeping tests passing

Zero Runtime Dependencies

AllFrame only depends on:

Tokio - Async runtime
Hyper - HTTP server
std - Rust standard library

No hidden bloat. No dependency hell.

Clean Architecture

Dependencies flow inward only:

Presentation → Application → Domain ← Infrastructure

This is enforced at compile time by AllFrame's macros.

Performance

AllFrame targets TechEmpower Round 23 benchmarks in future releases:

Metric	Target	Status
JSON serialization	> 500k req/s	📋 Planned
Single query	> 100k req/s	📋 Planned
Multiple queries	> 50k req/s	📋 Planned
Binary size	< 8 MB	✅ Achieved (<2 MB)

Note: Performance benchmarking is planned for Q2 2025. Current focus is on feature completeness and correctness. All functionality is production-ready with comprehensive test coverage (225 tests passing).
