| <p>This module contains all the Serde support for serializing Rust structures |
| into TOML documents (as strings). Note that some top-level functions here |
| are also provided at the top of the crate.</p> |
| <p>Note that the TOML format has a restriction that if a table itself contains |
| tables, all keys with non-table values must be emitted first. This is |
| typically easy to ensure happens when you’re defining a <code>struct</code> as you can |
| reorder the fields manually, but when working with maps (such as <code>BTreeMap</code> |
| or <code>HashMap</code>) this can lead to serialization errors. In those situations you |
| may use the <code>tables_last</code> function in this module like so:</p> |
