Description
Rust users are often unfamiliar with arrow and learning arrow can be a significant bottleneck to using lancedb. We could make it easier to import / export values by having the users create structs defining the record (similar to pydantic). In rust this is typically done with serde and there is a https://docs.rs/serde_arrow/latest/serde_arrow/ crate that we can investigate. The end result should be something like...
#[derive(Serialize, Deserialize, Debug)]
struct Location {
x: f64,
y: f64,
}
#[derive(Serialize, Deserialize, Debug)]
struct MyRecord {
score: f32,
caption: String,
location: Location,
clip: Vec<f64>,
}
...
tbl.add(data_source::from_structs(&[
MyRecord { score: 32.0, caption: "my caption".to_string(), clip: vec![1.0, 2.0, 3.0], location: Location { x: 0.0, y: 0.0 } }
])).execute().await.unwrap();
