Struct wasmi::GlobalRef

source · [−]

pub struct GlobalRef(_);

Expand description

Reference to a global variable (See GlobalInstance for details).

This reference has a reference-counting semantics.

Methods from Deref<Target = GlobalInstance>

source

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.

source

pub fn get(&self) -> RuntimeValue

Get the value of this global variable.

source

pub fn is_mutable(&self) -> bool

Returns if this global variable is mutable.

Note: Imported and/or exported globals are always immutable.

source

pub fn value_type(&self) -> ValueType

Returns value type of this global variable.

🔬 This is a nightly-only experimental API. (toowned_clone_into)

Uses borrowed data to replace owned data, usually by cloning. Read more
