//! # Used to interact with the [Model Endpoints](https://replicate.com/docs/reference/http#models.get).
//!
//! The model module contains all the functionality for interacting with the model endpoints of the Replicate API.
//! Currently supports the following endpoint:
//! * [Get Model](https://replicate.com/docs/reference/http#models.get)
//! * [Get Model Versions](https://replicate.com/docs/reference/http#models.versions.get)
//! * [List Model Versions](https://replicate.com/docs/reference/http#models.versions.list)
//! * [Delete Model Version](https://replicate.com/docs/reference/http#models.versions.delete)
//!
//! # Example
//! ```
//! use replicate_rust::Replicate;
//! let replicate = Replicate::new();
//!
//! // Run the model and wait for the result in a blocking manner.
//! let result = replicate.run(version, inputs);
//!
//! match replicate.models.get(String::from("replicate"), String::from("hello-world")) {
//!    Ok(result) => println!("Success : {:?}", result),
//!   Err(e) => println!("Error : {}", e),
//! };
//! ```
