HTTP response conversion. + +## Features + +- **Domain-Specific Errors**: Organized error types for different application domains (Database, SSH, Environment) +- **Axum Integration**: Automatic conversion to HTTP responses with appropriate status codes +- **Type Safety**: Strong typing with `thiserror` for clear error hierarchies +- **Automatic Logging**: Built-in tracing integration for error logging +- **Result Type Alias**: Convenient `Result` type for consistent error handling +- **Error Propagation**: Seamless error conversion using the `?` operator + +## Usage + +Add this crate to your workspace or local dependencies: + +```toml +[dependencies] +err = { path = "../err" } +``` + +### Basic Example + +```rust +use err::{AppError, DatabaseError, Result}; + +async fn get_user(id: u64) -> Result { + let user = database + .query("SELECT * FROM users WHERE id = $1") + .bind(id) + .await?; // DatabaseError automatically converts to AppError + + user.ok_or_else(|| DatabaseError::NotFound(format!("User {id}")).into()) +} +``` + +### Axum Handler + +```rust +use axum::{Json, extract::Path}; +use err::Result; + +async fn user_handler( + Path(user_id): Path +) -> Result> { + let user = get_user(user_id).await?; + Ok(Json(user)) +} +``` + +When an error occurs, it automatically converts to a JSON response: + +```json +{ + "status": 404, + "error": "database_not_found", + "message": "Resource not found" +} +``` + +## Error Types + +### AppError + +The main error enum that wraps all domain-specific errors: + +```rust +pub enum AppError { + Database(DatabaseError), + Ssh(SshError), + Environment(EnvironmentError), + ServerError(String), + BindError(String), +} +``` + +### DatabaseError + +Handles database-related errors: + +- `ConnectionError` - Database connection failures (503 Service Unavailable) +- `QueryError` - Query execution failures (500 Internal Server Error) +- `AuthenticationError` - Database auth failures (401 Unauthorized) +- `NotFound` - Resource not found (404 Not Found) +- `ConfigError` - Database configuration issues (500 Internal Server Error) + +**Example:** +```rust +use err::DatabaseError; + +// Automatic conversion from SurrealDB errors +let result = db.query("SELECT * FROM users").await?; + +// Manual error creation +return Err(DatabaseError::NotFound("User not found".into()).into()); +```

Replace the old internal `sys::health` modules with `hlt` usage: update AppState to hold a HealthRegistry, migrate DB health checker and Axum handler to use the new API, and wire the registry in initialization. Update Cargo workspace to include the new crate. --- Cargo.lock | 15 +++ Cargo.toml | 13 +-- crates/hlt/Cargo.toml | 20 ++++ crates/hlt/src/lib.rs | 12 +++ crates/hlt/src/models.rs | 184 +++++++++++++++++++++++++++++++ crates/hlt/src/registry.rs | 179 ++++++++++++++++++++++++++++++ crates/hlt/src/traits.rs | 60 +++++++++++ crates/hlt/tests/integration.rs | 186 ++++++++++++++++++++++++++++++++ src/dbs/health.rs | 28 ++--- src/dbs/mod.rs | 1 + src/main.rs | 1 - src/rts/health.rs | 108 +++++++++++++------ src/sys/config/state.rs | 5 +- src/sys/health/components.rs | 21 ---- src/sys/health/mod.rs | 6 -- src/sys/health/models.rs | 24 ----- src/sys/health/traits.rs | 7 -- src/sys/init.rs | 19 ++-- src/sys/mod.rs | 1 - 19 files changed, 764 insertions(+), 126 deletions(-) create mode 100644 crates/hlt/Cargo.toml create mode 100644 crates/hlt/src/lib.rs create mode 100644 crates/hlt/src/models.rs create mode 100644 crates/hlt/src/registry.rs create mode 100644 crates/hlt/src/traits.rs create mode 100644 crates/hlt/tests/integration.rs delete mode 100644 src/sys/health/components.rs delete mode 100644 src/sys/health/mod.rs delete mode 100644 src/sys/health/models.rs delete mode 100644 src/sys/health/traits.rs diff --git a/Cargo.lock b/Cargo.lock index 020e782..838605b 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -385,6 +385,7 @@ dependencies = [ "env", "err", "futures", + "hlt", "serde", "serde_json", "ssh2", @@ -1448,6 +1449,20 @@ version = "0.4.3" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "7f24254aa9a54b5c858eaee2f5bccdb46aaf0e486a595ed5fd8f86ba55232a70" +[[package]] +name = "hlt" +version = "0.1.0" +dependencies = [ + "async-trait", + "axum", + "chrono", + "futures", + "serde", + "serde_json", + "tokio", + "tracing", +] + [[package]] name = "hmac" version = "0.12.1" diff --git a/Cargo.toml b/Cargo.toml index b9c7790..65c92c1 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -10,14 +10,15 @@ serde.workspace = true serde_json.workspace = true tracing.workspace = true tokio.workspace = true +chrono.workspace = true # Our crates err.workspace = true -env.workspace = true - +env.workspace = true +hlt.workspace = true # Other dependencies async-trait = "0.1.89" -chrono = "0.4.42" + dotenvy = "0.15.7" futures = "0.3.31" ssh2 = "0.9.5" @@ -32,7 +33,7 @@ tracing-subscriber = { version = "0.3.20", features = ["env-filter", "json"] } [workspace] resolver = "3" -members = ["crates/env", "crates/err",] +members = ["crates/env", "crates/err", "crates/hlt" ] # Shared dependencies across all crates @@ -40,12 +41,12 @@ members = ["crates/env", "crates/err",] axum = "0.8.6" serde = { version = "1.0.228", features = ["derive"] } serde_json = "1.0.145" +chrono = "0.4.42" tracing = "0.1.41" tokio = { version = "1.47.1", features = ["macros", "rt-multi-thread"] } err = { path = "crates/err" } env = { path = "crates/env" } - - +hlt = { path = "crates/hlt" } # Profile settings apply to entire workspace diff --git a/crates/hlt/Cargo.toml b/crates/hlt/Cargo.toml new file mode 100644 index 0000000..a561262 --- /dev/null +++ b/crates/hlt/Cargo.toml @@ -0,0 +1,20 @@ +[package] +name = "hlt" +version = "0.1.0" +edition = "2024" + +[dependencies] +# Workspace dependencies +axum.workspace = true +serde.workspace = true +serde_json.workspace = true +tokio.workspace = true +tracing.workspace = true + +# Additional dependencies +async-trait = "0.1.89" +chrono.workspace = true +futures = "0.3.31" + +[dev-dependencies] +tokio = { workspace = true, features = ["macros", "rt", "time"] } diff --git a/crates/hlt/src/lib.rs b/crates/hlt/src/lib.rs new file mode 100644 index 0000000..538e0d3 --- /dev/null +++ b/crates/hlt/src/lib.rs @@ -0,0 +1,12 @@ +//! # hlt - Health Check Framework +//! +//!
