Struct QueryResponse 

pub struct QueryResponse {
    pub status: ResponseStatus,
    pub results: Vec<QueryResult>,
    pub took: Option<f64>,
    pub error: Option<ErrorDetail>,
}

Contains query results, execution metadata, and optional error information. Matches the server’s SqlResponse structure.

Fields

status: ResponseStatus

Query execution status (“success” or “error”)

results: Vec<QueryResult>

Array of result sets, one per executed statement

took: Option<f64>

Query execution time in milliseconds (with fractional precision)

error: Option<ErrorDetail>

Error details if status is “error”

Implementations

impl QueryResponse

pub fn success(&self) -> bool

Returns true if the query executed successfully.

pub fn is_token_expired(&self) -> bool

Returns true if the error is a TOKEN_EXPIRED error.

pub fn rows(&self) -> Vec<Vec<KalamCellValue>>

Returns the first result’s rows, if any (as arrays).

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

Returns the first result’s rows as HashMaps (column name → value).

pub fn first_row_as_map(&self) -> Option<HashMap<String, KalamCellValue>>

Returns the first row as a HashMap, if any.

pub fn row_count(&self) -> usize

Returns the first result’s row count.

pub fn column_index(&self, column_name: &str) -> Option<usize>

Get column index by name from schema.

pub fn get_value(&self, column_name: &str) -> Option<KalamCellValue>

Get a value from the first row by column name.

pub fn get_i64(&self, column_name: &str) -> Option<i64>

Get an i64 value from the first row by column name.

Handles both numeric values and string-encoded integers (for Int64 precision). The backend serializes Int64 as strings to preserve precision in JSON.

pub fn get_string(&self, column_name: &str) -> Option<String>

Get a string value from the first row by column name.

Trait Implementations

impl Clone for QueryResponse

fn clone(&self) -> QueryResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryResponse

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QueryResponse

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for QueryResponse

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.
