Theodlz commented on issue #435:

HOWEVER, here is another bug that's probably related, and much easier to
reproduce:
```rust
use apache_avro::{AvroSchema, Writer};
use serde::{Deserialize, Serialize};
#[derive(Deserialize, Serialize, AvroSchema)]
pub enum Color { G, R, I }
#[derive(Deserialize, Serialize, AvroSchema)]
pub struct A {
pub time: f64,
pub color: Option<Color>,
}
fn main() {
let test = A {
time: 123.0,
color: Some(Color::R),
};
let schema = A::get_schema();
let mut writer = Writer::with_codec(
&schema,
Vec::new(),
apache_avro::Codec::Snappy,
)
.unwrap();
writer.append_ser(test).unwrap();
}
```
Here, it shows that it can't generate a proper Avro definition for an option
of an enum (`Option<Color>` in this example), as it fails with the error:
```rust
Error { details: Failed to serialize field 'color' for record
Record(RecordSchema { name: Name { name: "A", namespace: None }, aliases: None,
doc: None, fields: [RecordField { name: "time", doc: None, aliases: None,
default: None, schema: Double, order: Ascending, position: 0,
custom_attributes: {} }, RecordField { name: "color", doc: None, aliases: None,
default: None, schema: Union(UnionSchema { schemas: [Null, Enum(EnumSchema {
name: Name { name: "Color", namespace: None }, aliases: None, doc: None,
symbols: ["G", "R", "I"], default: None, attributes: {} })], variant_index:
{Null: 0, Enum: 1} }), order: Ascending, position: 1, custom_attributes: {} }],
lookup: {"color": 1, "time": 0}, attributes: {} }): Failed to serialize value
of type unit struct using schema Enum(EnumSchema { name: Name { name: "Color",
namespace: None }, aliases: None, doc: None, symbols: ["G", "R", "I"], default:
None, attributes: {} }): Color. Cause: Expected Null or Union schema. Got: Enum
}
```
So here, it clearly mixes up optional and non optional field
