struct SerializedNodeHeader<D> {
bytes: [u8; 34],
_marker: PhantomData<D>,
}
Expand description
A packed representation of all the fixed-size fields in a NodeInfo
.
This stores in one byte array:
- The
Fingerprint
in theNodeInfo
- The
Fingerprint
inDepNode
that is in thisNodeInfo
- The
DepKind
’s discriminant (a u16, but not all bits are used…) - The byte width of the encoded edges for this node
- In whatever bits remain, the length of the edge list for this node, if it fits
