Enum JsonPathCast 

pub enum JsonPathCast {
    None,
    Signed,
    Double,
    Decimal,
}

Cast applied when a nested composite field is rendered through JSON storage.

PostgreSQL stores composite fields natively and ignores this value. SQLite’s json_extract preserves scalar number types, so it also ignores this value. MySQL JSON extraction returns JSON/text, so the dialect uses this hint to keep numeric ordering numeric instead of lexicographic.

Variants

None

No cast; keep the extracted scalar as text/native JSON scalar.

Signed

Cast to a signed integer.

Double

Cast to a floating-point number.

Decimal

Cast to a wide decimal value.

Trait Implementations

impl Clone for JsonPathCast

fn clone(&self) -> JsonPathCast

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JsonPathCast

impl Debug for JsonPathCast

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

Formats the value using the given formatter.

impl Eq for JsonPathCast

impl PartialEq for JsonPathCast

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