Struct QueryResult 

pub struct QueryResult {
    pub schema: Vec<SchemaField>,
    pub rows: Option<Vec<Vec<KalamCellValue>>>,
    pub named_rows: Option<Vec<HashMap<String, KalamCellValue>>>,
    pub row_count: usize,
    pub message: Option<String>,
    pub as_user: Option<String>,
}

Individual query result within a SQL response.

Fields

schema: Vec<SchemaField>

Schema describing the columns in the result set. Each field contains: name, data_type (KalamDataType), and index.

rows: Option<Vec<Vec<KalamCellValue>>>

The result rows as arrays of values (ordered by schema index). Populated by the server; cleared client-side once named_rows is built.

named_rows: Option<Vec<HashMap<String, KalamCellValue>>>

Rows as maps keyed by column name (column → KalamCellValue).

Populated client-side by [populate_named_rows] from schema + rows. When present, SDKs should prefer this over positional rows.

row_count: usize

Number of rows affected or returned.

message: Option<String>

Optional message for non-query statements.

as_user: Option<String>

Effective user identifier this statement executed as.

Implementations

impl QueryResult

pub fn column_names(&self) -> Vec<String>

Get column names from schema.

pub fn row_as_map( &self, row_idx: usize, ) -> Option<HashMap<String, KalamCellValue>>

Get a row as a HashMap by index (for convenience).

pub fn rows_as_maps(&self) -> Vec<HashMap<String, KalamCellValue>>

Get all rows as HashMaps (column name → value).

pub fn populate_named_rows(&mut self)

Build named_rows from schema + rows, then clear positional rows.

After this call the result contains only the named-column representation so SDKs can iterate named_rows directly instead of performing the schema → map transformation themselves.

Trait Implementations

impl Clone for QueryResult

fn clone(&self) -> QueryResult

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QueryResult

fn deserialize<__D>( __deserializer: __D, ) -> Result<QueryResult, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for QueryResult

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
