 # OFREP Provider for OpenFeature

A Rust implementation of the OpenFeature OFREP provider, enabling dynamic
feature flag evaluation in your applications.

This provider allows to connect to any feature flag management system that supports OFREP.

#### Installation
Add the dependency in your `Cargo.toml`:
```bash
cargo add open-feature-ofrep
cargo add open-feature
```
Then integrate it into your application:

```rust
use std::time::Duration;
use open_feature::provider::FeatureProvider;
use open_feature::EvaluationContext;
use open_feature_ofrep::{OfrepProvider, OfrepOptions};
use reqwest::header::{HeaderMap, HeaderValue};

#[tokio::main]
async fn main() {
    let mut headers = HeaderMap::new();
    headers.insert("color", HeaderValue::from_static("yellow"));

    let provider = OfrepProvider::new(OfrepOptions {
        base_url: "http://localhost:8016".to_string(),
        headers: headers.clone(),
        connect_timeout: Duration::from_secs(4),
        ..Default::default()
    }).await.unwrap();

    let context = EvaluationContext::default()
                    .with_targeting_key("user-123")
                    .with_custom_field("color", "yellow");

    let result = provider.resolve_bool_value("isColorYellow", &context).await.unwrap();
    println!("Flag value: {}", result.value);
}
```

#### Configuration Options
Configurations can be provided as constructor options. The following options are supported:

| Option                                  | Type / Supported Value            | Default                             |

| headers                                 | HeaderMap                         | Empty Map                           |
