//! # Tract
//!
//! Tiny, no-nonsense, self contained, portable SharedTensor and ONNX inference.
//!
//! ## Example
//!
//! ```
//! # extern crate tract_core;
//! # extern crate ndarray;
//! # fn main() {
//! use tract_core::*;
//! use tract_core::model::*;
//! use tract_core::model::dsl::*;
//!
//! // build a simple model that just add 3 to each input component
//! let mut model = Model::default();
//!
//! let input = model.add_source("input").unwrap();
//! let three = model.add_const("three".to_string(), 3f32.into()).unwrap();
//! let add = model.add_node("add".to_string(),
//!     Box::new(tract_core::ops::math::Add::default())).unwrap();
//!
//! model.add_edge(OutletId::new(input, 0), InletId::new(add, 0)).unwrap();
//! model.add_edge(OutletId::new(three, 0), InletId::new(add, 1)).unwrap();
//!
//! // we build an execution plan. default input and output are inferred from
//! // the model graph
//! let plan = SimplePlan::new(&model).unwrap();
//!
//! // run the computation.
//! let input = ndarray::arr1(&[1.0f32, 2.5, 5.0]);
//! let mut outputs = plan.run(tvec![input.into()]).unwrap();
//!
//! // take the first and only output tensor
//! let mut tensor = outputs.pop().unwrap();
//!
//! // unwrap it as array of f32
//! let tensor = tensor.to_array_view::<f32>().unwrap();
//! assert_eq!(tensor, ndarray::arr1(&[4.0, 5.5, 8.0]).into_dyn());
//! # }
//! ```
//!
//! While creating a model from Rust code is usefull for testing the library,
//! real-life use-cases will usually load a SharedTensor or ONNX model using
//! tract-tf or tract-onnx crates.
//!
