To map enums between a column and a struct field

• some MySQL boilerplate code is required.
• the enum must implement the ToString and FromStr traits.

For the first I made a little crate mysql_enum and for the later several crates exit. Here an example with strum:

With this in Cargo.toml

[dependencies]
mysql_enum = "0.1"
strum = "0.22"
strum_macros = "0.22"

you can attribute your enums:

use mysql_enum::MysqlEnum;
use strum_macros::{Display, EnumString};

#[derive(PartialEq, EnumString, Display, MysqlEnum)]
enum Mood {
   Happy,
   Sad
} 

Now Mood can be used:

#[derive (Debug, Toql)]
struct User {
    id : u64,
    name: Option<string>
    mood: Option<Mood>
}
