Struct ResultSet 

pub struct ResultSet { /* private fields */ }

Implementations

impl ResultSet

pub fn num_rows(&self) -> usize

pub fn schema(&self) -> &Schema

pub fn raw_rows(&self) -> &[Vec<Option<String>>]

Returns the unparsed JSON-format cells exactly as received from ScopeDB.

pub fn to_values(&self) -> Result<Vec<Vec<Value>>, Error>

Converts all result cells to their typed Rust representation.

pub fn into_values(self) -> Result<Vec<Vec<Value>>, Error>

Consumes the result set and returns typed rows.

pub fn to_objects(&self) -> Result<Vec<ResultObject>, Error>

Converts all rows to maps keyed by unique output column names.

Duplicate output names are rejected instead of silently discarding a value. Use ResultSet::to_values when a query intentionally returns duplicate column names.

pub fn into_objects(self) -> Result<Vec<ResultObject>, Error>

Consumes the result set and returns rows keyed by output column name.

examples/statement.rs (line 22)

async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = common::client()?;

    let result = client.query("SELECT 1 AS ready").await?;
    let rows = result.into_objects()?;
    println!("rows: {rows:?}");

    // Keep the handle when an application needs progress, cancellation, or a
    // durable statement ID before waiting for the result.
    let mut handle = client.statement("SELECT 2 AS value").submit().await?;
    let statement_id = handle.statement_id();
    println!(
        "statement {statement_id} submitted: {:?}",
        handle.snapshot()
    );
    let status = handle.refresh().await?;
    println!("statement {statement_id}: {status:?}");
    let result = handle.wait().await?;
    println!("handle rows: {:?}", result.into_objects()?);
    Ok(())
}

pub fn first(&self) -> Result<Option<ResultObject>, Error>

Returns the first row keyed by output column name, or None when empty.
