This crate implements a plain text serializer and deserializer. It can only serialize and deserialize primitives and derivatives thereof (like basic enums or newtypes). It internally uses the FromStr and Display trait to convert objects around.

To parse a value from a string the from_str helper can be used:

assert_eq!(serde_plain::from_str::<i32>("42").unwrap(), 42);

This is particularly useful if enums are in use:

use serde::Deserialize;

#[derive(Deserialize, Debug, PartialEq, Eq)]
pub enum MyEnum {
    VariantA,
    VariantB,
}

assert_eq!(serde_plain::from_str::<MyEnum>("VariantA").unwrap(), MyEnum::VariantA);

The inverse is also possible with to_string:

assert_eq!(serde_plain::to_string(&true).unwrap(), "true");
