export const StringFromNullish = Schema.optionalToOptional(
  Schema.NullOr(Schema.String),
  Schema.NonEmptyString,
  {
    decode: (input) => {
      if (Option.isNone(input)) {
        return Option.none();
      }
      const value = input.value;
      if (value === null || value.trim() === '') {
        return Option.none();
      }
      return Option.some(value);
    },
    encode: identity,
  },
);

export const MyBrandTypeFromNullish = Schema.optionalToOptional(
  Schema.NullOr(Schema.String.pipe(Schema.fromBrand(MyBrand))),
  Schema.NonEmptyString,
...

export const MyOtherBrandTypeFromNullish = Schema.optionalToOptional(
  Schema.NullOr(Schema.String.pipe(Schema.fromBrand(MyOtherBrand))),
  Schema.NonEmptyString,
