enum

Ecto.Enum — map a user-defined Gleam type to string or integer DB values.

Elixir’s Ecto.Enum maps atoms; Gleam has no atoms, so the user supplies an explicit mapping between their own variant type a and the DB representation. No parameterized-type behaviour is needed — this is a plain LodeType constructor.

type Status { Active Archived } let status_type = enum.string_enum(“status”, [#(Active, “active”), #(Archived, “archived”)])
