Struct wasmer::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) -> GlobalType

Create a new Global variable

Usage:

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

// 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.

pub unsafe fn resolve(
    &self,
    pos: usize,
    resolver: <GlobalType as Archive>::Resolver,
    out: *mut <GlobalType as Archive>::Archived
)

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

impl Clone for GlobalType

pub 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

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

Formats the value using the given formatter.

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

pub fn deserialize<__D>(
    __deserializer: __D
) -> Result<GlobalType, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<GlobalType, __D> for <GlobalType as Archive>::Archived where
    __D: Fallible + ?Sized,
    Type: Archive,
    <Type as Archive>::Archived: Deserialize<Type, __D>,
    Mutability: Archive,
    <Mutability as Archive>::Archived: Deserialize<Mutability, __D>, 

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

Deserializes using the given deserializer

impl Display for GlobalType

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

Formats the value using the given formatter.

impl Hash for GlobalType

pub 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, 

Feeds a slice of this type into the given Hasher.

impl MemoryUsage for GlobalType

pub fn size_of_val(&self, visited: &mut dyn MemoryUsageTracker) -> usize

Returns the size of the referenced value in bytes.

impl PartialEq<GlobalType> for GlobalType

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

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

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

This method tests for !=.

impl Serialize for GlobalType

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

Serialize this value into the given Serde serializer.

impl<__S> Serialize<__S> for GlobalType where
    __S: Fallible + ?Sized,
    Type: Serialize<__S>,
    Mutability: Serialize<__S>, 

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

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