Quo is a cross-platform variable dumper designed to make debugging easier. It receives data from your application and
displays it in a clean desktop interface, allowing you to inspect complex values in real-time without cluttering your
terminal or browser console.
### Noteworthy features
- **Debug-only**: The macro only executes in debug mode (`#[cfg(debug_assertions)]`). In release builds, it compiles to nothing, ensuring zero overhead.
- **Multiple arguments**: Inspect multiple variables in a single call.
### Installation
Add `quo-rust` to your `Cargo.toml` under `dev-dependencies`:
```toml
[dev-dependencies]
quo-rust = "0.1.2"
```
### Usage
Import the macro and pass variables to inspect:
```rust
use quo_rust::quo;
#[derive(Debug)]
struct User {
id: u32,
username: String,
}
fn main() {
let user_id = 42;
let user = User { id: 1, username: "jdoe".to_string() };
// Dump a single variable
quo!(user_id);
// Dump multiple variables at once
quo!(user_id, user);
}
```
### Configuration
You can customize the Quo server address using environment variables at compile time:
- `QUO_HOST`: The host where Quo is running (default: `http://127.0.0.1`, Quo always listens on 127.0.0.1 so changing this has no use).
- `QUO_PORT`: The port Quo is listening on (default: `7312`)
> The correct port can be found by opening the Quo client in the bottom left.
> Note: The Quo client always uses 127.0.0.1 as host, it is **not** recommended to have it set to any other host.
You can set these in your `Cargo.toml` as follows
```toml
[env]
QUO_HOST="http://127.0.0.1"
QUO_PORT="7312"
```
