Struct Imm 

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

A constant, in the immediate table.

The bits and nothing else. An integer is stored two’s complement in as many of the low bits as its type is wide, and a floating point value is stored as its bit pattern, so the same table holds both and the type on the result says how to read it. That keeps a bit-preserving answer for a NaN payload, which a value of a Rust floating type would not.

Implementations

impl Imm

pub const fn bits(self) -> u128

The bits, as they are stored.

pub const fn from_bits(bits: u128) -> Self

An immediate holding these bits.

pub fn int(value: i128, ty: Type) -> Self

An integer, with the bits above ty cleared.

A value is stored in exactly the width its type has, so two immediates are equal when they are the same value, which is what lets an equality on the table stand in for an equality on the numbers.

Panics

Panics if ty is not an integer type.

pub const fn unsigned(self) -> u128

The value read as unsigned.

pub fn signed(self, ty: Type) -> i128

The value read as signed, with the sign bit of ty extended.

Panics

Panics if ty is not an integer type.
