## Usage
**Client:**
```rust
use bromine::prelude::*;
use tokio::net::TcpListener;
/// Callback ping function
async fn handle_ping(ctx: &Context, event: Event) -> Result<()> {
println!("Received ping event.");
ctx.emit("pong", ()).await?;
Ok(())
}
#[tokio::main]
async fn main() {
// create the client
let ctx = IPCBuilder::::new()
.address("127.0.0.1:2020")
// register callback
.on("ping", callback!(handle_ping))
.build_client().await.unwrap();
// emit an initial event
let response = ctx.emit("ping", ()).await?.await_response(&ctx).await?;
}
```
**Server:**
```rust
use bromine::prelude::*;
use tokio::net::TcpListener;
// create the server
#[tokio::main]
async fn main() {
IPCBuilder::::new()
.address("127.0.0.1:2020")
// register callback
.on("ping", callback!(ctx, event, async move {
println!("Received ping event.");
Ok(())
}))
.build_server().await.unwrap();
}
```
### Namespaces
**Client:**
```rust
use bromine::prelude::*;
use tokio::net::TcpListener;
// create the client
#[tokio::main]
async fn main() {
let ctx = IPCBuilder::::new()
.address("127.0.0.1:2020")
// register namespace
.namespace("mainspace-client")
// register callback (without macro)
.on("ping", |_ctx, _event| Box::pin(async move {
println!("Received ping event.");
Ok(())
}))
.build()
.build_client().await.unwrap();
// emit an initial event
let response = ctx.emit_to("mainspace-server", "ping", ()).await?
.await_response(&ctx).await?;
}
```
**Server:**
```rust
use bromine::prelude::*;
use tokio::net::TcpListener;
// create the server
pub struct MyNamespace;
impl MyNamespace {
async fn ping(_ctx: &Context, _event: Event) -> Result<()> {
println!("My namespace received a ping");
Ok(())
}
}
impl NamespaceProvider for MyNamespace {
fn name() -> &'static str {"my_namespace"}
fn register(handler: &mut EventHandler) {
events!(handler,
"ping" => Self::ping
);
}
}
#[tokio::main]
async fn main() {
IPCBuilder::::new()
.address("127.0.0.1:2020")
// register namespace
.namespace("mainspace-server")
// register callback
.on("ping", |_ctx, _event| Box::pin(async move {
println!("Received ping event.");
Ok(())
}))
.build()
.add_namespace(namespace!(MyNamespace))
.build_server().await.unwrap();
}
