serde_yml 0.0.12

A robust Rust library that simplifies the serialization and deserialization of Rust data structures to and from YAML format using the widely-used Serde framework.
//!
//! Example for the `serialize` and `deserialize` functions in the `singleton_map_recursive` module.
//!
//! This example demonstrates the usage of the `serialize` and `deserialize` functions
//! from the `singleton_map_recursive` module to serialize and deserialize a
//! struct field that contains an enum with multiple variants into a YAML map
//! with a single key-value pair, where the key is the enum variant name and the
//! value is the inner value of the enum variant.
//!
