oxide-sdk 0.1.0

# Oxide SDK

Guest-side SDK for building WebAssembly applications that run inside the
[Oxide browser](https://github.com/niklabh/oxide) — a binary-first browser
that fetches and executes `.wasm` modules instead of HTML/JavaScript.

This crate provides safe Rust wrappers around the raw host-imported functions
exposed by the `"oxide"` import module. It has **zero dependencies**.

## Quick Start

Add `oxide-sdk` to your guest crate:

```toml
[package]
name = "my-oxide-app"
version = "0.1.0"
edition = "2021"

[lib]
crate-type = ["cdylib"]

[dependencies]
oxide-sdk = "0.1"
```

Write your app:

```rust
use oxide_sdk::*;

#[no_mangle]
pub extern "C" fn start_app() {
    log("Hello from Oxide!");
    canvas_clear(30, 30, 46, 255);
    canvas_text(20.0, 40.0, 28.0, 255, 255, 255, "Welcome to Oxide");
}
```

Build for wasm and open in the Oxide browser:

```bash
rustup target add wasm32-unknown-unknown
cargo build --target wasm32-unknown-unknown --release
```
