Enum arithmetic_eval::ValueType

#[non_exhaustive]
pub enum ValueType {
    Prim,
    Bool,
    Function,
    Tuple(usize),
    Object,
    Array,
    Ref,
}

Possible high-level types of Values.

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.

Prim

Primitive type other than Boolean.

Bool

Boolean value.

Function

Function value.

Tuple(usize)

Tuple of a specific size.

Object

Object.

Array

Array (a tuple of arbitrary size).

This variant is never returned from Value::value_type(); at the same time, it is used for error reporting etc.

Ref

Opaque reference to a value.

Trait Implementations

impl Clone for ValueType

fn clone(&self) -> ValueType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueType

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

Formats the value using the given formatter.

impl Display for ValueType

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

Formats the value using the given formatter.

impl Hash for ValueType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ValueType

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
