Suggested change

	column_desc: Some(ProstColumnDesc {
	column_id: 0,
	name: ROWID_NAME.to_string(),
	field_descs: vec![],
	column_type: Some(DataType::Int32.to_protobuf()),
	type_name: String::new(),
	}),
	column_desc: Some(ProstColumnDesc::new_atomic(
	ROWID_NAME.to_string(),
	DataType::Varchar.to_protobuf(),
	"",
	}),

Why didn't you just refactor all occurrences of direct struct instantiation?

and actully you can simplify more:

pub fn new_atomic(data_type: DataType, name: impl Into<String>, column_id: i32) -> Self {
        Self {
            column_type: Some(data_type.to_protobuf()), // you can get away from to_protobuf() every where
            column_id,
            name: name.into(), // use Into<String> for arguments that can possibily be either &str or String,
            ..Default::default()
        }
    }
