Enum CapHashOrRef 

pub enum CapHashOrRef {
    Hash(CapHash),
    Ref(CapRef),
}

Slot/field reference: either a content-addressed blob in cache.blobs or a mutable working entry in cache.instances.

SSZ note: CapHashOrRef’s HashTreeRoot impl is hand-rolled (see below), not derived. The pass-through semantics — Hash(h) hashes to h — let a freshly-published cap substitute for a Ref reference without changing the hash of any cap that holds it. The Ref arm panics: callers must settle a cap graph before hashing it. Encode mirrors HashTreeRoot (panic on Ref); Decode rejects the Ref selector (no directory context).

Not Copy: the Ref(CapRef) arm carries a refcounted handle, so the enum is Clone-only.

Trait Implementations

impl Clone for CapHashOrRef

fn clone(&self) -> CapHashOrRef

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CapHashOrRef

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decode for CapHashOrRef

fn is_ssz_fixed_len() -> bool

true iff this type is fixed-length.

fn ssz_fixed_len() -> usize

Number of bytes this type occupies in the fixed-length portion of a container encoding. Variable-length types return BYTES_PER_LENGTH_OFFSET.

fn from_ssz_bytes(bytes: &[u8]) -> Result<Self, DecodeError>

Decode a full instance from bytes, rejecting trailing input.

impl Encode for CapHashOrRef

fn is_ssz_fixed_len() -> bool

true iff this type is fixed-length (no variable-length fields).

fn ssz_fixed_len() -> usize

Number of bytes this type occupies in the fixed-length portion of a container encoding. For variable-length types this returns BYTES_PER_LENGTH_OFFSET (i.e. the size of the offset slot).

fn ssz_bytes_len(&self) -> usize

Total size of self when serialized.

fn ssz_append(&self, buf: &mut Vec<u8>)

Append the encoding of self to buf.

fn is_basic_type() -> bool

true for “basic” SSZ types (uintN, bool), which pack adjacent elements into shared 32-byte chunks for merkleization. Composite types (containers, lists, structs) return false (the default).

fn as_ssz_bytes(&self) -> Vec<u8>

Serialize into a fresh Vec<u8> allocated through the global allocator.

impl Hash for CapHashOrRef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl HashTreeRoot for CapHashOrRef

fn hash_tree_root<D: Digest<OutputSize = U32>>(&self) -> [u8; 32]

Compute the hash tree root using D as the underlying hash.

impl PartialEq for CapHashOrRef

fn eq(&self, other: &CapHashOrRef) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
