Diesel enum derive

Please note that this crate is aimed to be simple and stick to a simple usage, no fancy configuration, only Pg with Text fields.

For a more advanced usage, see this crate: adwhit/diesel-derive-enum

Features

This crate has two features:

• heck uses heck::ToSnakeCase to transform enum values. This feature is enabled by default.
• plain keep enum values, use with default-features = false.

Usage

#[derive(DieselEnum)]
pub enum Role {
    Admin,
    User,
}

The method Role::Admin.db_value() returns the database representation of this variant.

Version compatibility

This crate is intended to be used with the Diesel crate, but it's not a direct dependency of this crate. Because of this reason, the version dependencies are not always clear, which can cause weird compilation errors in case of a mismatch.

The version compatibility is specified in the following table:

Diesel version	Diesel-enum-derive version
<=1.4.8	0.1.4
>=2.0.0	1.0.0
