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, 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 version of this type.

type Resolver = GlobalTypeResolver

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

fn resolve(
    &self,
    pos: usize,
    resolver: Self::Resolver,
    out: &mut MaybeUninit<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,
    Archived<Type>: Deserialize<Type, __D>,
    Mutability: Archive,
    Archived<Mutability>: Deserialize<Mutability, __D>, 

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

Feeds a slice of this type into the given Hasher.

impl MemoryUsage for GlobalType

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

Returns the size of the referenced value in bytes.

impl PartialEq<GlobalType> 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: &GlobalType) -> bool

This method tests for !=.

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.

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

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

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