Function serialize 

pub fn serialize<T, S>(
    value: &T,
    serializer: S,
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>
where
    T: Serialize,
    S: Serializer,

Serialize a value as a singleton map.

For enums, this serializes the variant as a map where the key is the variant name and the value is the variant’s data.

Examples

use noyalib::with::singleton_map;
use serde::{Deserialize, Serialize};

#[derive(Debug, Serialize, Deserialize)]
enum Action {
    Start,
    Stop { graceful: bool },
}

#[derive(Debug, Serialize, Deserialize)]
struct Command {
    #[serde(with = "singleton_map")]
    action: Action,
}
