Crate arcly_http 

arcly-http — NestJS ergonomics meets Rust safety & speed.

This is the facade crate: it re-exports the always-compiled arcly-http-core foundation and, behind Cargo features, the optional subsystems. Nothing heavy compiles by default — enable only what you use:

Feature	Brings in	Heavy deps
(default)	DI, routing, RequestContext, auth, resilience, observability, OpenAPI	—
data / db-*	multi-tenant data layer + drivers	sqlx / sea-orm / diesel
compliance	PII masking + field encryption	aes-gcm
realtime	WebSocket gateways + SSE	—
messaging	event consumer mesh	—
full	everything (what docs.rs builds)	all

Most applications only need use arcly_http::prelude::*;.

Modules

app

Launch contract.

auth

Identity & Access — JWT, signed cookies, server-side sessions, OAuth2, guards.

cache

Per-route response cache, driven by #[CacheTTL(N)] on the route method.

compliance

Data governance — cross-cutting compliance machinery.

cookie

HTTP cookie signing and extraction via HMAC-SHA256.

core

data

Datasource contracts: tenant-scoped pools + read/write splitting.

docs

Self-documenting API surface: OpenAPI 3 spec assembly + Swagger UI.

event

In-process async event bus — actually lock-free on the emit path.

guards

Request guards — composable preconditions evaluated before a handler runs.

http

Zero-axum public HTTP types.

interceptors

Aspect-oriented interceptors.

messaging

Event consumer mesh — the inbound half of the event architecture.

oauth

OAuth 2.0 provider abstraction.

observability

openapi

OpenAPI 3.0 spec generation + a tiny Swagger UI page.

pipeline

Unified request provenance — one answer to “who is this unit of work, which trace does it continue, which tenant does it belong to?” shared by every transport: HTTP requests, WebSocket handshakes, and consumer-mesh messages.

plugins

Third-party plugin ecosystem.

prelude

use arcly_http::prelude::*; brings in everything a user needs.

realtime

Real-time protocol engine: WebSocket gateways + Server-Sent Events.

resilience

Lock-free circuit breaker + the BreakerOpen sentinel surfaced when the breaker is OPEN.

security

Security headers middleware – a Helmet.js equivalent for arcly-http.

session

Server-side session store abstraction.

testing

First-class testing support for user-land code — the missing half of the NestJS-DX promise (@nestjs/testing equivalent).

transport

Transport-agnostic envelope + error types shared across the request pipeline and the messaging subsystem.

validation

Validated<T> – type-branded, deserialized-and-validated request payload.

web

Structs

RequestContext

The one and only context passed to every handler.

Enums
