Trait butane::FieldType

pub trait FieldType: ToSql + FromSql {
    type RefType: ToSql + ?Sized;

    const SQLTYPE: SqlType;
}

Type suitable for being a database column.

Required Associated Types

type RefType: ToSql + ?Sized

Reference type. Used for ergonomics with String (which has reference type str). For most, it is Self
