Simon Gittins updated AVRO-3901:
--------------------------------
Description:
Want to be able to serde to/from an enum containing structs for a union schema
containing record(s):
{code:json}
{
"name": "C",
"type": "record",
"fields": [
...
\{"name": "field_union", "type": ["A", "B"]},
...
]
}
{code}
With code like:
{code:C}
struct A \{...}
struct B \{...}
#[serde(untagged)]
enum UnionAB \{ A(A), B(B)}
struct C {
...
field_union: UnionAB,
...
}
{code}
Likewise, want to be able to serde where the schema includes null:
{code:json}
{
"name": "E",
"type": "record",
"fields": [
...
\{"name": "field_union", "type": ["A", "null", "B"]},
...
]
}
{code}
{code:C}
#[serde(untagged)]
enum UnionANoneB {
A(A),
None,
B(B),
}
{code}
