Enum ValueKind

pub enum ValueKind {
    Nil = 0,

    Int = 2,
    BigInt = 3,
    Float = 4,

}

Value kinds returned by HostApi::value_kind.

Over the FFI these travel as plain u32 - convert with as u32 / ValueKind::from_u32. The host-side mapping (and the coverage test guarding that every interpreter value maps to one of these) lives in the feature-gated plugin module in the interpreter crate.

Variants

Nil = 0

The nil value.

Bool = 1

A boolean.

Int = 2

An integer that fits in an i64 (int_get succeeds).

BigInt = 3

An integer that does not fit in an i64 (int_get fails; use value_display/value_str).

Float = 4

A float.

Rational = 5

A rational number.

String = 6

A string (string_get succeeds).

List = 7

A list (list_len/list_get succeed).

Tuple = 8

A tuple.

Dict = 9

A dict.

Set = 10

A set.

Range = 11

A range.

StopIteration = 12

The StopIteration sentinel - what __next__ returns when an iterator is exhausted.

Instance = 13

A plain class instance (fields via attr_get/attr_set, methods via invoke_method).

Class = 14

A class (instantiate via call_value).

Function = 15

A callable function value (closure, native function, or bound method) - use call_value.

Module = 16

A module.

Exception = 17

An exception instance.

Generator = 18

A generator.

Iterator = 19

A list/tuple/range/template iterator (drive via invoke_method with __next__).

Other = 20

VM-internal values a plugin should never meaningfully receive.

Implementations

impl ValueKind

pub const fn from_u32(code: u32) -> Self

Trait Implementations

impl Clone for ValueKind

fn clone(&self) -> ValueKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ValueKind

impl Debug for ValueKind

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

Formats the value using the given formatter.

impl Eq for ValueKind

impl PartialEq for ValueKind

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

Equality operator ==.

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

Inequality operator !=.
