#### Description

    final class GIRepository.FieldInfo : GObject.TypeInstance
    {
      /* No available fields */
    }

A `GIFieldInfo` struct represents a field of a struct, union, or object.

The `GIFieldInfo` is fetched by calling `gi_struct_info_get_field()`, `gi_union_info_get_field()` or `gi_object_info_get_field()`.

A field has a size, type and a struct offset associated and a set of flags, which are currently `GI_FIELD_IS_READABLE` or `GI_FIELD_IS_WRITABLE`.

See also: `GIStructInfo`, `GIUnionInfo`, `GIObjectInfo`.
