Struct TypedScalar 

#[repr(C)]
pub struct TypedScalar {
    pub kind: ScalarKind,
    pub payload_lo: u64,
    pub payload_hi: u64,
}

Type-preserving scalar value for VM↔JIT boundary exchange.

Carries an explicit type discriminator (kind) so that integer 42 and float 42.0 are distinguishable even when their f64 bit patterns would be identical.

payload_hi is zero for all types smaller than 128 bits.

Fields

kind: ScalarKind

payload_lo: u64

payload_hi: u64

Second 64-bit word — only used for I128/U128. Zero otherwise.

Implementations

impl TypedScalar

pub fn i64(v: i64) -> Self

Create an I64 scalar.

pub fn f64(v: f64) -> Self

Create an F64 scalar from a value.

pub fn f64_from_bits(bits: u64) -> Self

Create an F64 scalar from raw bits.

pub fn bool(v: bool) -> Self

Create a Bool scalar.

pub fn none() -> Self

Create a None scalar.

pub fn unit() -> Self

Create a Unit scalar.

pub fn i8(v: i8) -> Self

Create an I8 scalar.

pub fn u8(v: u8) -> Self

Create a U8 scalar.

pub fn i16(v: i16) -> Self

Create an I16 scalar.

pub fn u16(v: u16) -> Self

Create a U16 scalar.

pub fn i32(v: i32) -> Self

Create an I32 scalar.

pub fn u32(v: u32) -> Self

Create a U32 scalar.

pub fn u64(v: u64) -> Self

Create a U64 scalar.

pub fn f32(v: f32) -> Self

Create an F32 scalar.

pub fn as_i64(&self) -> Option<i64>

Extract as i64 (only valid if kind is an integer type). Returns None for U64 values > i64::MAX (use as_u64() instead).

pub fn as_u64(&self) -> Option<u64>

Extract as u64 (only valid if kind is an unsigned integer type).

pub fn as_f64(&self) -> Option<f64>

Extract as f64 (only valid if kind is F64 or F32).

pub fn as_bool(&self) -> Option<bool>

Extract as bool (only valid if kind is Bool).

pub fn to_f64_lossy(&self) -> Option<f64>

Interpret this scalar as an f64 regardless of kind (for numeric comparison). Integer kinds are cast; float kinds use their stored value; non-numeric returns None.

Trait Implementations

impl Clone for TypedScalar

fn clone(&self) -> TypedScalar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypedScalar

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

Formats the value using the given formatter.

impl PartialEq for TypedScalar

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

Tests for self and other values to be equal, and is used by ==.

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

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