Variants

Int

BigInt

Float

Text

Bool

Vector

Date

Timestamp

Interval

v7.9.25 — ::INTERVAL and ::TIMESTAMPTZ. mailrs follow-up H3a. Engine reuses the existing runtime-interval / timestamp paths (parse the text input, return the matching Value).

Timestamptz

Json

v7.9.25 — ::JSON and ::JSONB. SPG already has both types (v7.9.0); the cast just routes Text→Json with the requested OID for the wire layer.

Jsonb

RegType

v7.9.26 — ::regtype / ::regclass. Parsed for PG dump compatibility; engine surfaces as Unsupported with a hint to use SHOW TABLES or spg_table_ddl. mailrs F3b.

RegClass

TextArray

v7.10.11 — ::TEXT[]. Engine decodes the LHS Text into the PG external array form {a,b,NULL}.

IntArray

v7.11.13 — ::INT[] / ::BIGINT[]. Decodes PG external {1,2,3} or widens a TextArray whose elements are integer-shaped.

BigIntArray

Trait Implementations

impl Clone for CastTarget

fn clone(&self) -> CastTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CastTarget

impl Debug for CastTarget

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

Formats the value using the given formatter.

impl Display for CastTarget

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

Formats the value using the given formatter.

impl Eq for CastTarget

impl PartialEq for CastTarget

fn eq(&self, other: &CastTarget) -> 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.
