Enum ScalarValue

pub enum ScalarValue {
    Bool(bool),

    U16(u16),

Tagged union of scalar values

Numbers are always stored with 64-bit precision. Using smaller sizes would have no advantages regarding the size of this product type.

No conversions between signed/unsigned and integer/floating-point numbers to prevent using wrong types unintentionally! The same argument applies to boolean/integer conversions.

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.

impl PartialEq for Value

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