[GitHub] [arrow-rs] waymost opened a new issue, #3864: parquet_derive doesn't support Vec
waymost opened a new issue, #3864:
URL: https://github.com/apache/arrow-rs/issues/3864
**Describe the bug**
When I attempt to `#[derive(ParquetRecordWriter)]` on a struct that contains fields of type `Vec<u8>`, the proc-macro panics.
**To Reproduce**
```
#[derive(ParquetRecordWriter)]
pub struct Row {
foo: Vec<u8>,
}
```
results in
```
message: not implemented: Unsupported: Vec(
TypePath(
Path(
TypePath {
qself: None,
path: Path {
leading_colon: None,
segments: [
PathSegment {
ident: Ident {
ident: "u8",
span: #0 bytes(4505..4507),
},
arguments: None,
},
],
},
},
),
),
)
```
**Expected behavior**
Macro successfully generates the code to write a Vec<u8> to a parquet file.
**Additional context**
Support for `Vec<u8>` is explicitly mentioned in the `parquet_derive` readme, but a field of that type is not present in the integration test crate (separately, neither is `Uuid`).
