Derive Macro ergol::PgEnum

#[derive(PgEnum)]

Any enum that has no field on any variant can derive PgEnum in order to be usable in a #[ergol] struct.

Note:

Any enum needs to derive Debug in order to derive PgEnum, since deriving Debug is required in order to implement ToSql.

#[ergol]
pub struct Struct {
    #[id] pub id: i32,
    pub ok: IsOk,
}

#[derive(PgEnum, Debug)]
pub enum IsOk {
    IAmOk,
    IAmNotOk,
}
