Enum PublicNumber 

pub enum PublicNumber {
    Int(i64),
    Float(f64),
    Decimal(Decimal),
}

Represents a numeric value in SurrealDB

Numbers in SurrealDB can be integers, floating-point numbers, or decimal numbers. This enum provides type-safe representation for all numeric types.

Variants

Int(i64)

A 64-bit signed integer

Float(f64)

A 64-bit floating-point number

Decimal(Decimal)

A decimal number with arbitrary precision

impl Ord for Number

fn cmp(&self, other: &Number) -> Ordering
