[−][src]Struct wasmi::GlobalRef
Reference to a global variable (See GlobalInstance
for details).
This reference has a reference-counting semantics.
Methods from Deref<Target = GlobalInstance>
pub fn set(&self, val: RuntimeValue) -> Result<(), Error>
[src]
pub fn set(&self, val: RuntimeValue) -> Result<(), Error>
Change the value of this global variable.
Errors
Returns Err
if this global isn't mutable or if
type of val
doesn't match global's type.
pub fn get(&self) -> RuntimeValue
[src]
pub fn get(&self) -> RuntimeValue
Get the value of this global variable.
pub fn is_mutable(&self) -> bool
[src]
pub fn is_mutable(&self) -> bool
Returns if this global variable is mutable.
Note: Imported and/or exported globals are always immutable.
pub fn value_type(&self) -> ValueType
[src]
pub fn value_type(&self) -> ValueType
Returns value type of this global variable.
