Struct wasmer_types::GlobalType

pub struct GlobalType {
    pub ty: Type,
    pub mutability: Mutability,
}

WebAssembly global.

Fields

ty: Type

The type of the value stored in the global.

mutability: Mutability

A flag indicating whether the value may change at runtime.

Implementations

impl GlobalType

A WebAssembly global descriptor.

This type describes an instance of a global in a WebAssembly module. Globals are local to an Instance and are either immutable or mutable.

pub fn new(ty: Type, mutability: Mutability) -> Self

Create a new Global variable

Usage:

use wasmer_types::{GlobalType, Type, Mutability};

// An I32 constant global
let global = GlobalType::new(Type::I32, Mutability::Const);
// An I64 mutable global
let global = GlobalType::new(Type::I64, Mutability::Var);

Trait Implementations

impl Archive for GlobalType

where Type: Archive, Mutability: Archive,

type Archived = ArchivedGlobalType

The archived representation of this type.

type Resolver = GlobalTypeResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for GlobalType

fn clone(&self) -> GlobalType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GlobalType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GlobalType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<GlobalType, __D> for Archived<GlobalType>

where Type: Archive, <Type as Archive>::Archived: Deserialize<Type, __D>, Mutability: Archive, <Mutability as Archive>::Archived: Deserialize<Mutability, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<GlobalType, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for GlobalType

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

Formats the value using the given formatter.

impl Hash for GlobalType

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 PartialEq<ArchivedGlobalType> for GlobalType

where Type: Archive, Mutability: Archive, <Type as Archive>::Archived: PartialEq<Type>, <Mutability as Archive>::Archived: PartialEq<Mutability>,

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

impl PartialEq<GlobalType> for ArchivedGlobalType

where Type: Archive, Mutability: Archive, <Type as Archive>::Archived: PartialEq<Type>, <Mutability as Archive>::Archived: PartialEq<Mutability>,

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

impl PartialEq for GlobalType

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

impl<__S: Fallible + ?Sized> Serialize<__S> for GlobalType

where Type: Serialize<__S>, Mutability: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for GlobalType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
