Enum ResultType 

#[non_exhaustive]
pub enum ResultType {
    QueryResult,
    ChangedRows,
    Nothing,
    Invalid,
    Unknown(duckdb_result_type),
}

A fully iterable DuckDB query result. What kind of output a query produced.

Mirrors DuckDB’s duckdb_result_type. #[non_exhaustive] with Unknown so a value a future DuckDB adds is preserved rather than lost.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

QueryResult

The result carries queryable rows (SELECT, RETURNING, …).

ChangedRows

The result reports a changed-row count (INSERT/UPDATE/DELETE).

Nothing

The statement produced no result (many DDL statements).

Invalid

DUCKDB_RESULT_TYPE_INVALID.

Unknown(duckdb_result_type)

A type this build does not recognise; the raw value is preserved.

Implementations

impl ResultType

pub fn from_raw(raw: duckdb_result_type) -> ResultType

Classifies a raw duckdb_result_type, preserving unrecognised values.

Trait Implementations

impl Clone for ResultType

fn clone(&self) -> ResultType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ResultType

impl Debug for ResultType

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

Formats the value using the given formatter.

impl Eq for ResultType

impl Hash for ResultType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ResultType

fn eq(&self, other: &ResultType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
