Struct SerializedNodeHeader

struct SerializedNodeHeader<D> {
    bytes: [u8; 34],
    _marker: PhantomData<D>,
}

A packed representation of all the fixed-size fields in a NodeInfo.

This stores in one byte array:

• The Fingerprint in the NodeInfo
• The Fingerprint in DepNode that is in this NodeInfo
• 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

Fields

bytes: [u8; 34]

_marker: PhantomData<D>

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.
