Get a column value, returning an error if the column doesn’t exist or can’t be converted.

  • Floats: f32, f64
  • Boolean: bool
  • String: String
  • Any type implementing DeserializeOwned

use gpudb_api::Row;

let id: i64 = row.get("id")?;
let name: String = row.get("name")?;
let price: f64 = row.get("price")?;

Get a column value as an Option, returning None if the value is null.

Returns an error only if the column doesn’t exist.

use gpudb_api::Row;

let score: Option<f64> = row.get_opt("score")?;
if let Some(s) = score {
    println!("Score: {}", s);
}
