# Usage
A reqwest powered REST API client can be generated using `api_client_macro::generate!` provided the following syntax.
```rust
api_client_macro::generate!(ApiClient, {
user {
get_by_id: get "user/{id}" id: &str,
delete_by_id: delete "user/{id}" id: &str,
create: post "user",
list: get "users"
},
contact {
get_by_id: get "contact/{id}" id: &str,
delete_by_id: delete "contact/{id}" id: &str,
create: post "contact",
list: get "contact"
}
});
```
After compilation, the following code is available.
```rust
fn main() {
let client = ApiClientBuilder::new("<api-base-url>", None);
client.contact_create().body("<body>").send().unwrap();
client.contact_get_by_id("<id>").send().unwrap();
client.user_list().query(&[("email", "<email>")]).send().unwrap();
}
```
