Trait wasmer::Exportable

pub trait Exportable<'a>: Sized {
    fn to_export(&self) -> Export;
    fn get_self_from_extern(
        _extern: &'a Extern
    ) -> Result<&'a Self, ExportError>;
    fn into_weak_instance_ref(&mut self);
}

This trait is used to mark types as gettable from an Instance.

Required methods

fn to_export(&self) -> Export

This function is used when providedd the Extern as exportable, so it can be used while instantiating the Module.

fn get_self_from_extern(_extern: &'a Extern) -> Result<&'a Self, ExportError>

Implementation of how to get the export corresponding to the implementing type from an Instance by name.

fn into_weak_instance_ref(&mut self)

Convert the extern internally to hold a weak reference to the InstanceRef. This is useful for preventing cycles, for example for data stored in a type implementing WasmerEnv.
