Data Types

GraphQL only has these built-in scalar types:

• Int: A signed 32‐bit integer.
• Float: A signed double-precision floating-point value.
• String: A UTF‐8 character sequence.
• Boolean: true or false.

The SeaORM type system supports a richer set of types, including:

• Date, Time, Datetime: will be mapped to String
• Decimal, BigDecimal: will be mapped to String
• Uuid: will be mapped to String
• Json: will be mapped to a custom scalar type Json

MySQL / Postgres Enums

MySQL / Postgres enums are supported with SeaORM's ActiveEnum.

For example, the following Rust enum would be mapped to a GraphQL enum:

#[derive(Debug, Clone, PartialEq, Eq, EnumIter, DeriveActiveEnum)]
#[sea_orm(rs_type = "String", db_type = "Enum", enum_name = "mpaa_rating")]
pub enum MpaaRating {
    #[sea_orm(string_value = "G")]
    G,
    #[sea_orm(string_value = "PG")]
    Pg,
    #[sea_orm(string_value = "PG-13")]
    Pg13,
    #[sea_orm(string_value = "R")]
    R,
    #[sea_orm(string_value = "NC-17")]
    Nc17,
}

enum MpaaRatingEnum {
  G
  PG
  PG13
  R
  NC17
}
