Enum NumericWidth 

#[repr(u8)]
pub enum NumericWidth {
    I8 = 0,
    I16 = 1,
    I32 = 2,
    I64 = 3,
    U8 = 4,
    U16 = 5,
    U32 = 6,
    U64 = 7,
    F32 = 8,
    F64 = 9,
}

Numeric width tag for compact typed opcodes (AddTyped, SubTyped, etc.).

Encodes the operand width so a single opcode family can handle all numeric types. The discriminant values are part of the bytecode ABI and must remain stable.

Variants

I8 = 0

I16 = 1

I32 = 2

I64 = 3

U8 = 4

U16 = 5

U32 = 6

U64 = 7

F32 = 8

F64 = 9

Implementations

impl NumericWidth

pub const ALL: [Self; 10]

pub const fn is_integer(self) -> bool

pub const fn is_float(self) -> bool

pub const fn is_signed(self) -> bool

Whether this is a signed integer type.

pub const fn is_unsigned(self) -> bool

Whether this is an unsigned integer type.

pub const fn bits(self) -> u32

Number of bits for this width.

pub const fn mask(self) -> u64

Bit mask for the integer value range.

pub fn from_int_width(w: IntWidth) -> Self

Convert from IntWidth (shape-ast) to NumericWidth.

pub fn to_int_width(self) -> Option<IntWidth>

Convert to IntWidth (shape-ast). Returns None for F32/F64/I64.

Trait Implementations

impl Clone for NumericWidth

fn clone(&self) -> NumericWidth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericWidth

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NumericWidth

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NumericWidth

fn eq(&self, other: &NumericWidth) -> 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.

impl Serialize for NumericWidth

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
