use mongod::{AsField, Field};

#[derive(Bson, Mongo)]
#[mongo(collection="users")]
pub struct User {
    pub name: String,
}

impl AsField<UserField> for User {}

pub enum UserField {
    Name,
}

impl Field for UserField {}

impl From<UserField> for String {
    fn from(field: UserField) -> String {
        match field {
            UserField::Name => "name".to_owned(),
        }
    }
}
