# act-zero-ext
Extention macros for act-zero
## IntoActorResult Usage
Will wrap a function that returns a `Result<T,E>` into a function that returns a `ActorResult<Result<T, E>>`. Also works with `Option<T>` and returns `ActorResult<Option<T>>`.
Example:
```rust
pub struct App {}
impl App {
#[act_zero_ext::into_actor_result]
async fn hello(&self, name: String) -> Result<String, Box<dyn std::error::Error>> {
Ok(format!("Hello, {}!", name))
}
}
```
Will be converted to:
```rust
pub struct App {}
impl App {
pub async fn hello(&self, name: String) -> ActorResult<Result<String, Box<dyn std::error::Error>>> {
let result = self.do_hello(name).await;
Produces::Ok(result)
}
async fn do_hello(&self, name: String) -> Result<String, Box<dyn std::error::Error>> {
Ok(format!("Hello, {}!", name))
}
}
```
### Option Example
```rust
pub struct App {}
impl App {
#[act_zero_ext::into_actor_result]
async fn find_user(&self, id: u64) -> Option<String> {
if id > 0 {
Some(format!("User {}", id))
} else {
None
}
}
}
```
Will be converted to:
```rust
pub struct App {}
impl App {
pub async fn find_user(&self, id: u64) -> ActorResult<Option<String>> {
let result = self.do_find_user(id).await;
Produces::ok(result)
}
async fn do_find_user(&self, id: u64) -> Option<String> {
if id > 0 {
Some(format!("User {}", id))
} else {
None
}
}
}
```
