rustc/vendor/tabled-0.15.0/examples/builder.rs

//! This example demonstrates an alternative method for creating a [`Table`].
//! [`Builder`] is an efficient implementation of the [builder design pattern](https://en.wikipedia.org/wiki/Builder_pattern).
//!
//! > The intent of the Builder design pattern is to separate the construction of a complex object from its representation.
//! > -- <cite>Wikipedia</cite>
//!
//! * Note how [Builder] can be used to define a table's shape manually
//!  and can be populated through iteration if it is mutable. This flexibility
//! is useful when you don't have direct control over the datasets you intend to [table](tabled).
