## Installation
Add this to your `Cargo.toml`:
```toml
[dependencies]
devintest_api = "0.0.2"
```
Or install via cargo:
```sh
cargo add devintest_api
```
## Reference
A full reference for this library is available [here](https://github.com/devalog/rust-sdk/blob/HEAD/./reference.md).
## Usage
Instantiate and use the client with the following:
```rust
use devintest_api::prelude::*;
#[tokio::main]
async fn main() {
let config = ClientConfig {
..Default::default()
};
let client = ApiClient::new(config).expect("Failed to build client");
client
.imdb
.create_movie(
&CreateMovieRequest {
title: "title".to_string(),
rating: 1.1,
},
None,
)
.await;
}
```
## Errors
When the API returns a non-success status code (4xx or 5xx response), an error will be returned.
```rust
match client.imdb.create_movie(None)?.await {
Ok(response) => {
println!("Success: {:?}", response);
},
Err(ApiError::HTTP { status, message }) => {
println!("API Error {}: {:?}", status, message);
},
Err(e) => {
println!("Other error: {:?}", e);
}
}
```
## Advanced
### Retries
The SDK is instrumented with automatic retries with exponential backoff. A request will be retried as long
as the request is deemed retryable and the number of retry attempts has not grown larger than the configured
retry limit (default: 2).
A request is deemed retryable when any of the following HTTP status codes is returned:
- [408](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/408) (Timeout)
- [429](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/429) (Too Many Requests)
- [5XX](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/500) (Internal Server Errors)
Use the `max_retries` method to configure this behavior.
```rust
let response = client.imdb.create_movie(
Some(RequestOptions::new().max_retries(3))
)?.await;
```
### Timeouts
The SDK defaults to a 30 second timeout. Use the `timeout` method to configure this behavior.
```rust
let response = client.imdb.create_movie(
Some(RequestOptions::new().timeout_seconds(30))
)?.await;
```
### Additional Headers
You can add custom headers to requests using `RequestOptions`.
```rust
let response = client.imdb.create_movie(
Some(
RequestOptions::new()
.additional_header("X-Custom-Header", "custom-value")
.additional_header("X-Another-Header", "another-value")
)
)?
.await;
```
### Additional Query String Parameters
You can add custom query parameters to requests using `RequestOptions`.
```rust
let response = client.imdb.create_movie(
Some(
RequestOptions::new()
.additional_query_param("filter", "active")
.additional_query_param("sort", "desc")
)
)?
.await;
```
