Enum Type 

pub enum Type<'a> {
    Word,
    Long,
    Single,
    Double,
    Zero,
    Byte,
    SignedByte,
    UnsignedByte,
    Halfword,
    SignedHalfword,
    UnsignedHalfword,
    Aggregate(&'a TypeDef<'a>),
}

QBE types used to specify the size and representation of values.

QBE has a minimal type system with base types and extended types. Base types are used for temporaries, while extended types can be used in aggregate types and data definitions.

Examples

use qbe::Type;

// Base types
let word = Type::Word;     // 32-bit integer
let long = Type::Long;     // 64-bit integer
let single = Type::Single; // 32-bit float
let double = Type::Double; // 64-bit float

// Extended types
let byte = Type::Byte;     // 8-bit value
let halfword = Type::Halfword; // 16-bit value

// Get type sizes in bytes
assert_eq!(word.size(), 4);
assert_eq!(byte.size(), 1);

Type Conversions

use qbe::Type;

// Convert extended type to corresponding base type
let base = Type::Byte.into_base();
assert_eq!(base, Type::Word);

// Convert to ABI-compatible type for function parameters
let abi = Type::SignedByte.into_abi();
assert_eq!(abi, Type::Word);

Implementations

impl Type<'_>

pub fn into_abi(self) -> Self

Returns a C ABI type. Extended types are converted to closest base types

pub fn into_base(self) -> Self

Returns the closest base type

pub fn size(&self) -> u64

Returns byte size for values of the type

pub fn align(&self) -> u64

Returns byte alignment for values of the type

Trait Implementations

impl<'a> Clone for Type<'a>

fn clone(&self) -> Type<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Type<'a>

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

Formats the value using the given formatter.

impl Display for Type<'_>

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

Formats the value using the given formatter.

impl<'a> Hash for Type<'a>

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<'a> Ord for Type<'a>

fn cmp(&self, other: &Type<'a>) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for Type<'a>

fn eq(&self, other: &Type<'a>) -> 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<'a> PartialOrd for Type<'a>

fn partial_cmp(&self, other: &Type<'a>) -> 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.
