Struct twasmi::GlobalRef [−][src]
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]
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]
Get the value of this global variable.
pub fn is_mutable(&self) -> bool[src]
Returns if this global variable is mutable.
Note: Imported and/or exported globals are always immutable.
pub fn value_type(&self) -> ValueType[src]
Returns value type of this global variable.
