Attribute Macro butane_codegen::butane_type

#[butane_type]

Attribute macro which marks a type as being available to butane for use in models.

May be used on type aliases, structs, or enums. Except when used on type aliases, it must be given a parameter specifying the SqlType it can be converted to.

E.g.

#[butane_type]
pub type CurrencyAmount = f64;

#[butane_type(Text)]
pub enum Currency {
  Dollars,
  Pounds,
  Euros,
}
impl ToSql for Currency {
  fn to_sql(&self) -> SqlVal {
     SqlVal::Text(
         match self {
             Self::Dollars => "dollars",
             Self::Pounds => "pounds",
             Self::Euros => "euros",
         }
         .to_string())
 }
}
