Enum Kind 

#[repr(u8)]
pub enum Kind {
    Nil = 0,
    Bool = 1,
    Int = 2,
    Float = 3,
    Char = 4,
    Str = 5,
    Array = 6,
    Map = 7,
    Object = 8,
    Function = 9,
    Cell = 10,
    Iter = 11,
    Error = 12,
    Coroutine = 13,
    Reference = 14,
}

The kind of a dynamic value: what Inst::TypeOf returns and Inst::IsKind tests.

Dynamic integers are 64-bit signed and dynamic floats are binary64, whatever their boxed representation.

Examples

use bytecode_lang::Kind;

assert_eq!(Kind::Map.code(), 7);
assert_eq!(Kind::from_code(5), Some(Kind::Str));
assert_eq!(Kind::Object.to_string(), "object");

Variants

Nil = 0

nil: the absent value, and the null reference.

Bool = 1

A boolean.

Int = 2

A 64-bit signed integer.

Float = 3

A binary64 float.

Char = 4

A Unicode scalar value.

Str = 5

An immutable byte string.

Array = 6

An array.

Map = 7

An ordered hash map.

Object = 8

A struct instance.

Function = 9

A callable: a closure, a function, or a host function.

Cell = 10

A mutable cell.

Iter = 11

An iterator.

Error = 12

A runtime error value (see Inst::ErrCode).

Coroutine = 13

A coroutine: a suspendable stack of frames (generators, async tasks; see Inst::CoroNew).

Reference = 14

A reference (PHP &): a box holding one dynamic value, made by Inst::NewRef or by taking a reference to a container slot (Inst::DRefIndex, Inst::DRefProp). It is a cell of dyn (cell_get/cell_set read and write it), and a container slot holding one is transparent: reads and writes of the slot go through to the reference’s value (specs/LSB.md §5.16).

Implementations

impl Kind

pub const ALL: &'static [Kind]

Every value, in code order.

pub const fn from_code(code: u8) -> Option<Self>

The value with this stable code, or None if no value has it.

pub const fn code(self) -> u8

The stable code this value is encoded as.

pub const fn name(self) -> &'static str

The lowercase name the disassembler prints.

Trait Implementations

impl Clone for Kind

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Kind

impl Debug for Kind

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

Formats the value using the given formatter.

impl Display for Kind

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

Formats the value using the given formatter.

impl Eq for Kind

impl Hash for Kind

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 Ord for Kind

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Kind

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Kind

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
