Struct Value 

pub struct Value(/* private fields */);

The core Value type for all Sema data. NaN-boxed: stored as 8 bytes. Floats stored directly, everything else encoded in quiet-NaN payload space.

impl Value

pub fn raw_bits(&self) -> u64

Get the raw bits (for debugging/testing).

pub unsafe fn from_raw_bits(bits: u64) -> Value

Construct a Value from raw NaN-boxed bits.

Safety

Caller must ensure bits represents a valid NaN-boxed value. For immediate types (nil, bool, int, symbol, keyword, char), this is always safe. For heap-pointer types, the encoded pointer must be valid and have its Rc ownership accounted for (i.e., the caller must ensure the refcount is correct).

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

Get the NaN-boxing tag of a boxed value (0-63). Returns None for non-boxed values (floats).

pub fn as_native_fn_ref(&self) -> Option<&NativeFn>

Borrow the underlying NativeFn without bumping the Rc refcount. SAFETY: The returned reference is valid as long as this Value is alive.

pub fn is_float(&self) -> bool

Check if this is a float (non-boxed).

pub fn view(&self) -> ValueView

Pattern-match friendly view of this value. For heap types, this bumps the Rc refcount.

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
