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

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
