Struct Global 

pub struct Global(/* private fields */);

A Wasm global.

Implementations

impl Global

pub fn new( store: &mut Store, type_: GlobalType, val: Val, ) -> Result<Self, GlobalError>

Creates a new Global with the given GlobalType and initialization Val in the given Store.

Errors

If the ValType of the initialiation Val does not match the ValType of the Global to be created.

Panics

If the initialization Val is not owned by the given Store.

pub fn type_(self, store: &Store) -> GlobalType

Returns the GlobalType of this Global.

pub fn get(self, store: &Store) -> Val

Returns the value of this Global.

pub fn set(self, store: &mut Store, val: Val) -> Result<(), GlobalError>

Sets the value of this Global to the given Val.

Errors

• If the global is immutable.
• If the ValType of the given Val does not match the ValType of this Global.

Panics

If the given Val is not owned by the given Store.

Trait Implementations

impl Clone for Global

fn clone(&self) -> Global

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Global

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

Formats the value using the given formatter.

impl From<Global> for ExternVal

fn from(global: Global) -> Self

Converts to this type from the input type.

impl Hash for Global

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 Global

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

Tests for self and other values to be equal, and is used by ==.

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

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