//! # espocrm-rs
//!
//! The `espocrm-rs` crate provides an API Client for EspoCRM. This client is based on the official PHP API client provided by the EspoCRM team.
//! You can find this client [here](https://docs.espocrm.com/development/api-client-php/).
//!
//! ## Getting started
//! To get started you'll have to provide the URL where EspoCRM is located at. You will also have to set the way you want to authenticate with EspoCRM.
//! This can be done in one of the following ways:
//! - Username+Password
//! - API Key
//! - HMAC (Recommended)
//!
//! The following example creates an EspoApiClient with HMAC authorization
//! ```rust
//! use espocrm_rs::EspoApiClient;
//!
//! let client = EspoApiClient::new("https://espocrm.example.com")
//!     .set_api_key("Your API Key here")
//!     .set_secret_key("Your API Secret")
//!     .build();
//! ```
//!
//! The following example creates an EspoApiClient with API Key authorization
//! ```rust
//! use espocrm_rs::EspoApiClient;
//! let client = EspoApiClient::new("https://espocrm.example.com")
//!     .set_api_key("Your API Key here")
//!     .build();
//! ```
//!
//! The following example creates an EspoApiClient with Username+Password authorization.
//! **This is highly discouraged!**
//! ```rust
//! use espocrm_rs::EspoApiClient;
//! let client = EspoApiClient::new("https://espocrm.example.com")
//!     .set_username("Your Username here")
//!     .set_password("Your Password here")
//!     .build();
//! ```
//!
//! # Making a GET request
//! To make a request, you need to know a couple things:
//! - The request method to use
//! - On what to perform the request
//! - Optionally, any data needed for the request
//!
//! Most of these things are laid out pretty well in the EspoCRM API documentation [here](https://docs.espocrm.com/development/api/)
//! ```rust
//! use espocrm_rs::{EspoApiClient, Params, Where, FilterType, Value, NoGeneric, Method};
//!
//! let params = Params::default()
//!     .set_offset(0)
//!     .set_where(vec![
//!         Where {
//!             r#type: FilterType::IsTrue,
//!             attribute: "exampleField".to_string(),
//!             value: None
//!         },
//!         Where {
//!             r#type: FilterType::ArrayAnyOf,
//!             attribute: "exampleField2".to_string(),
//!             value: Some(Value::array(vec![
//!                 Value::str("a"),
//!                 Value::str("b"),
//!                 Value::str("c")
//!             ]))
//!         }
//!     ])
//!     .build();
//!
//! let client = EspoApiClient::new("https://espocrm.example.com")
//!     .set_secret_key("Your Secret Key")
//!     .set_api_key("Your api key")
//!     .build();
//!
//! let result = client.request::<NoGeneric, &str>(Method::Get, "Contact", Some(params), None);
//! ```
//!
//! # Making a POST, PUT or DELETE request
//! These are all similar in working. They'll serialize your data into json using Serde's serialize trait
//!
//! ```rust
//! use espocrm_rs::{EspoApiClient, Method};
//! use serde::Serialize;
//!
//! #[derive(Serialize, Clone)]
//! struct MyData {
//!     some_value:         String,
//!     some_other_value:   i64
//! }
//!
//! let client = EspoApiClient::new("https://espocrm.example.com")
//!     .set_secret_key("Your Secret Key")
//!     .set_api_key("Your api key")
//!     .build();
//!
//! let data = MyData {
//!     some_value: "value".to_string(),
//!     some_other_value: 10
//! };
//!
//! let result = client.request(Method::Post, "Contact", None, Some(data));
//!```
//!
