Struct SQLResult 

pub struct SQLResult {
    pub kind: SQLResultKind,
    pub command_tag: Option<String>,
    pub columns: Vec<String>,
    pub column_types: Vec<Option<ColumnType>>,
    pub rows: Vec<ResultRow>,
    pub affected_rows: u64,
    /* private fields */
}

Fields

kind: SQLResultKind

Descriptor presence, including zero-column and empty row results.

command_tag: Option<String>

PostgreSQL command completion, including its command-specific row count. Execution sets this from the command that actually ran; row constructors leave it absent because rows alone do not identify a SQL command.

columns: Vec<String>

Column order as the SELECT clause specified.

column_types: Vec<Option<ColumnType>>

Statically bound SQL type for each output position. A missing entry represents a type that has not yet been resolved, never a type inferred from the first runtime value.

rows: Vec<ResultRow>

One row per result document, with the named columns in columns. Extra columns from _score etc. are included here too.

affected_rows: u64

Number of rows touched by an INSERT / UPDATE / DELETE.

Implementations

impl SQLResult

pub fn with_command_tag(self, tag: impl Into<String>) -> Self

Attach the completion chosen by the executing SQL command.

pub fn empty() -> Self

pub fn from_rows(columns: Vec<String>, rows: Vec<ResultRow>) -> Self

pub fn from_rows_with_positions( columns: Vec<String>, rows: Vec<ResultRow>, positional_rows: Option<Vec<Vec<Value>>>, ) -> Self

pub fn from_typed_rows_with_positions( columns: Vec<String>, column_types: Vec<Option<ColumnType>>, rows: Vec<ResultRow>, positional_rows: Option<Vec<Vec<Value>>>, ) -> Self

pub fn value_at(&self, row: usize, column: usize) -> Option<&Value>

Return a result value by row and output-column position.

Positional access is the canonical way to distinguish repeated output labels. Named rows remain available for compatibility with existing callers.

pub fn from_affected(affected: u64) -> Self

Trait Implementations

impl Clone for SQLResult

fn clone(&self) -> SQLResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SQLResult

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

Formats the value using the given formatter.

impl Default for SQLResult

fn default() -> SQLResult

Returns the “default value” for a type.
