Prima bridge pattern implementation for rust

Example

use prima_bridge::prelude::*;
use serde::Deserialize;

#[derive(Deserialize)]
struct DeserializableData {
    test: String
}

// using we make sure that `Bridge` get instantiated only once
fn bridge() -> &'static Bridge {
    static BRIDGE: OnceCell<Bridge> = OnceCell::new();
    BRIDGE.get_or_init(|| Bridge::new("https://prima.it/api"))
}

// Do not use expect in production! It will cause runtime errors. Use Result.
pub fn fetch_data() -> YourResult<DeserializableData> {
    Request::get(bridge())
        .send()?
        .get_data(&["nested", "selector"])? // response is {"nested": {"selector": {"data": "test"}}}
}           

To understand this example you should know:

• once_cell library providing the cell type
• Rust error handling to use ? and convert it to a custom error type. See for example thiserror
