Enum wasmtime_environ::wasmparser::StorageType

pub enum StorageType {
    I8,
    I16,
    Val(ValType),
}

Represents storage types introduced in the GC spec for array and struct fields.

Variants

I8

The storage type is i8.

I16

The storage type is i16.

Val(ValType)

The storage type is a value type.

Implementations

impl StorageType

pub fn is_packed(&self) -> bool

Is this a packed storage type, i.e. one that must be sign- or zero-extended when converted to a ValType?

pub fn unpack(&self) -> ValType

Unpack this storage type into the valtype that it is represented as on the operand stack.

Trait Implementations

impl Clone for StorageType

fn clone(&self) -> StorageType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageType

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

Formats the value using the given formatter.

impl Display for StorageType

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

Formats the value using the given formatter.

impl<'a> FromReader<'a> for StorageType

fn from_reader( reader: &mut BinaryReader<'a> ) -> Result<StorageType, BinaryReaderError>

Attempts to read Self from the provided binary reader, returning an error if it is unable to do so.

impl Hash for StorageType

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 PartialEq for StorageType

fn eq(&self, other: &StorageType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
