Enum JScalarKind 

#[non_exhaustive]
pub enum JScalarKind {
    I64,
    U64,
    F64,
    String,
    Bool,
}

Discriminant for the scalar variant carried in a JSON predicate operand.

V1 has exactly five accepted scalar kinds; new kinds may be added in future versions, hence #[non_exhaustive].

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.

I64

Exact signed-integer scalar.

U64

Exact unsigned-integer scalar.

F64

Finite binary64 scalar.

String

UTF-8 string scalar (eq/neq/in_/not_in only — no ordering).

Bool

Boolean scalar (eq/neq/in_/not_in only).

Trait Implementations

impl Clone for JScalarKind

fn clone(&self) -> JScalarKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JScalarKind

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

Formats the value using the given formatter.

impl PartialEq for JScalarKind

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