Those deserializers are used to deserialize tuple or struct variants from Content
which is used by internally tagged enums and by flatten
FlatMapDeserializer is reached in the following tests:
flatten::enum_::externally_tagged::newtype
flatten::enum_::externally_tagged::struct_from_map
flatten::enum_::externally_tagged::struct_from_seq
flatten::enum_::externally_tagged::tuple
ContentDeserializer is reached in the following tests:
test_enum_in_internally_tagged_enum
test_internally_tagged_struct_variant_containing_unit_variant
The Container struct
struct Container {
#[serde(flatten)]
enum_field: Enum,
}
enum Enum {
Tuple(u32, u32),
}
now can be serialized to JSON as
{ "enum_field": [1, 2] }
Deserialization already works
Fixes (1):
flatten::enum_::externally_tagged::tuple
