//! # `toml_edit`
//!
//! This crate allows you to parse and modify toml
//! documents, while preserving comments, spaces* and
//! relative order* or items.
//!
//! It is primarily tailored to the needs of [cargo-edit](https://github.com/killercup/cargo-edit/).
//!
//! # Example
//!
//! ```rust
//! use toml_edit::{Document, value};
//!
//! let toml = r#"
//! "hello" = 'toml!' # comment
//! ['a'.b]
//! "#;
//! let mut doc = toml.parse::<Document>().expect("invalid doc");
//! assert_eq!(doc.to_string(), toml);
//! // let's add a new key/value pair inside a.b: c = {d = "hello"}
//! doc["a"]["b"]["c"]["d"] = value("hello");
//! // autoformat inline table a.b.c: { d = "hello" }
//! doc["a"]["b"]["c"].as_inline_table_mut().map(|t| t.fmt());
//! let expected = r#"
//! "hello" = 'toml!' # comment
//! ['a'.b]
//! c = { d = "hello" }
//! "#;
//! assert_eq!(doc.to_string(), expected);
//! ```
//!
//! ## Limitations
//!
//! Things it does not preserve:
//!
//! * Different quotes and spaces around the same table key, e.g.
//!
//! ```text
//! [ 'a'. b]
//! [ "a"  .c]
//! [a.d]
//! ```
//!
//! will be represented as (spaces are removed, the first encountered quote type is used)
//!
//! ```text
//! ['a'.b]
//! ['a'.c]
//! ['a'.d]
//! ```
//!
//! * Children tables before parent table (tables are reordered by default, see [test]).
//! * Scattered array of tables (tables are reordered by default, see [test]).
//!
//! The reason behind the first limitation is that `Table` does not store its header,
//! allowing us to safely swap two tables
//! (we store a mapping in each table: child key -> child table).
//!
//! This last two limitations allow us to represent a toml document as a tree-like data structure,
//! which enables easier implementation of editing operations
//! and an easy to use and type-safe API. If you care about the above two cases,
//! you can use `Document::to_string_in_original_order()` to reconstruct tables in their original order.
//!
