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 = GlobalType

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.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

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

impl<__C: ?Sized> CheckBytes<__C> for GlobalType

where Type: CheckBytes<__C>, Mutability: CheckBytes<__C>,

type Error = StructCheckError

The error that may result from checking the type.

unsafe fn check_bytes<'__bytecheck>( value: *const Self, context: &mut __C, ) -> Result<&'__bytecheck Self, StructCheckError>

Checks whether the given pointer points to a valid value within the given context.

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<__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, Self: Sized,

Feeds a slice of this type into the given Hasher.

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::Resolver, __S::Error>

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