Ok @martin-g in my quest to write a test for this (I fail so far) I found
something that I clearly do not understand but which triggers the same Error
than my initial problem here.
Disclaimer : I'm not sure if they are related, but since I don't understand
how to fix this failing test below, I dunno...
Basically, you can't call `from_avro_datum` multiple times on the same
reader :
```rust
#[test]
fn test_from_avro_datum_multiple() {
let schema = Schema::parse_str(SCHEMA).unwrap();
let mut encoded: &'static [u8] = &[54, 6, 102, 111, 111];
let mut record = Record::new(&schema).unwrap();
record.put("a", 27i64);
record.put("b", "foo");
let expected = record.into();
from_avro_datum(&schema, &mut encoded, None).unwrap();
assert_eq!(
from_avro_datum(&schema, &mut encoded, None).unwrap(),
expected
);
```
Gives
```
thread 'reader::tests::test_from_avro_datum_multiple' panicked at 'called
`Result::unwrap()` on an `Err` value: ReadVariableIntegerBytes(Error { kind:
UnexpectedEof, message: "failed to fill whole buffer" })', src/reader.rs:408:54
```
