Enum ExportItem

source
pub enum ExportItem<T> {
    Index(T),
    Name(String),
}
Expand description

An index at which to find an item within a runtime instance.

Variants§

§

Index(T)

An exact index that the target can be found at.

This is used where possible to avoid name lookups at runtime during the instantiation process. This can only be used on instances where the module was statically known at compile time, however.

§

Name(String)

An item which is identified by a name, so at runtime we need to perform a name lookup to determine the index that the item is located at.

This is used for instantiations of imported modules, for example, since the precise shape of the module is not known.
