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>

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

Get the value of this global variable.

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

Returns value type of this global variable.
