Variants

AlreadyPresent

Fields

header: Header

return the Header so we can avoid doing clone of the data all the time

cached_reference: Option<Arc<Ref>>

the cached reference if it was already cached.

• None means the associated block is already in storage but not already in the cache;
• Some(ref) returns the local cached Ref of the block

result when the given header is already present in the local storage. The embedded cached_reference gives us the local cached reference is the header is already loaded in memory

MissingParent

Fields

header: Header

return back the Header so we can avoid doing a clone of the data all the time

the parent is missing from the local storage

HeaderWithCache

Fields

header: Header

return back the Header so we can avoid doing a clone of the data all the time

parent_ref: Arc<Ref>

return the locally stored parent’s Ref. Already cached in memory for future processing

The parent’s is already present in the local storage and is loaded in the local cache
