Enum Type

pub enum Type {
    I32,
    I64,
    F32,
    F64,
    V128,
    FuncRef,
    ExternRef,

}

Types in waffle’s IR.

These types correspond to (a subset of) the primitive Wasm value types: integers, floats, SIMD vectors, and function references (optionally typed).

Every SSA value in a function body has a Type, unless it is a tuple (multi-value or zero-value result).

Variants

I32

A 32-bit integer. Signedness is unspecified: individual operators specify how they handle sign.

I64

A 64-bit integer. Signedness is unspecified: individual operators specify how they handle sign.

F32

A 32-bit IEEE 754 floating point value. Semantics around NaNs are defined by individual operators; from the point of view of IR scaffolding, floating-point values are bags of bits.

F64

A 64-bit IEEE 754 floating point value. Semantics around NaNs are defined by individual operators; from the point of view of IR scaffolding, floating-point values are bags of bits.

V128

A 128-bit SIMD vector value. Lanes and lane types are specified by individual operators; from the point of view of IR scaffolding, SIMD vector values are bags of bits.

FuncRef

A function reference.

ExternRef

TypedFuncRef

Fields

nullable: bool

sig_index: Signature

Trait Implementations

impl Clone for Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Type

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Type

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

Formats the value using the given formatter.

impl From<RefType> for Type

fn from(ty: RefType) -> Self

Converts to this type from the input type.

impl From<Type> for RefType

fn from(ty: Type) -> RefType

Converts to this type from the input type.

impl From<Type> for ValType

fn from(ty: Type) -> ValType

Converts to this type from the input type.

impl From<ValType> for Type

fn from(ty: ValType) -> Self

Converts to this type from the input type.

impl Hash for Type

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 Ord for Type

fn cmp(&self, other: &Type) -> 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 PartialEq for Type

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

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

impl Serialize for Type

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Type

impl Eq for Type

impl StructuralPartialEq for Type
