Enum RuntimeKey 

pub enum RuntimeKey {
    Bool(bool),
    Integer(i64),
    FloatBits(u64),
    Str(String),
    Symbol(Symbol),
    ObjectIdentity(u64),
}

A table key derived from a runtime value rather than a kernel Symbol.

Guest languages use this when table/hash/map keys are ordinary values. The key remains policy-controlled so each language decides which values are admissible and how numeric values collapse or stay distinct.

Variants

Bool(bool)

Boolean key.

Integer(i64)

Integer key.

FloatBits(u64)

Floating-point key represented by its raw IEEE-754 bits.

Str(String)

Text key.

Symbol(Symbol)

Symbol key.

ObjectIdentity(u64)

Object identity key, local to this runtime process.

Implementations

impl RuntimeKey

pub fn from_value(cx: &mut Cx, value: &Value) -> Result<Option<Self>>

Derives a general-purpose key from value.

Nil and NaN are rejected with None; booleans, numbers, strings, and symbols become structural keys; every other value is keyed by object identity. Guest languages can call this from their own RuntimeKeyPolicy or provide a stricter mapping.

pub fn as_integer_index(&self) -> Option<i64>

Returns this key as a contiguous integer index when it is one.

pub fn as_expr(&self) -> Expr

Projects this key into an expression for inspection.

Trait Implementations

impl Clone for RuntimeKey

fn clone(&self) -> RuntimeKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeKey

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

Formats the value using the given formatter.

impl Eq for RuntimeKey

impl Hash for RuntimeKey

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 RuntimeKey

fn cmp(&self, other: &RuntimeKey) -> 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.

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RuntimeKey

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for RuntimeKey

fn partial_cmp(&self, other: &RuntimeKey) -> 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.
