Struct JournalEffector

pub struct JournalEffector {}
Available on crate feature journal only.
Expand description

The journal effector is an adapter that will be removed in a future refactor. Its purpose is to put the code that does mappings from WASM memory through its abstractions into concrete journal objects that can be stored. Instead of this what should be done is that the syscalls themselves can be represented as a strongly typed object that can be passed directly to the journal but in order to do this we require an extensive refactoring of the WASIX syscalls which is not in scope at this time.

Separating this out now makes it easier to eliminate later without hurting the journal event abstraction through leaking abstraction layers.
