## Documentation
- [API Documentation](https://docs.rs/arangodb_events_rs/)
## Features
- `async` Enables asynchronous `Handler::call` method
## Installation
Add the crate to your `Cargo.toml`:
```toml
arangodb_events_rs = "0.1.6"
```
## Usage
```rust
use arangodb_events_rs::api::DocumentOperation;
use arangodb_events_rs::{Handler, Trigger, HandlerContextFactory};
pub struct GlobalHandler;
pub struct GlobalHandlerContext {
pub data: u8,
}
impl Handler for GlobalHandler {
type Context = GlobalHandlerContext;
fn call(ctx: &GlobalHandlerContext, doc: &DocumentOperation) {
println!("{}", ctx.data); // 10
}
}
#[tokio::main]
async fn main() {
let mut trigger = Trigger::new_auth(
"http://localhost:8529/",
"database",
TriggerAuthentication::new("user", "password"),
);
trigger.subscribe::(
HandlerEvent::InsertOrReplace,
HandlerContextFactory::from(GlobalHandlerContext {
data: 10,
})
); // This subscribes for all Insert or Replace operations on the database
trigger.subscribe_to::(
HandlerEvent::Remove,
"accounts",
HandlerContextFactory::from(AccountHandlerContext {
data: 50,
})
); // This is gonna listen only for Remove operations over accounts table
trigger
.init()
.await
.expect("Error initializing ArangoDB Trigger");
loop {
trigger
.listen()
.await
.expect("Error on Trigger listener loop");
}
}
