Struct StateLeaf 

pub struct StateLeaf {
    pub blob_hash: CapHash,
    pub cap_hash: CapHash,
}

One state-root leaf: a (blob_hash, cap_hash) pair.

Encoded as the SSZ container { blob_hash: [u8;32], cap_hash: [u8;32] }. The leaf’s hash_tree_root is merkleize([blob_hash, cap_hash], 2) = hash(blob_hash || cap_hash) — equivalent to the legacy BMT leaf protocol but with SHA-256 instead of Blake2b.

Fields

blob_hash: CapHash

cap_hash: CapHash

Trait Implementations

impl Clone for StateLeaf

fn clone(&self) -> StateLeaf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateLeaf

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

Formats the value using the given formatter.

impl Encode for StateLeaf

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 HashTreeRoot for StateLeaf

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 StateLeaf

fn eq(&self, other: &StateLeaf) -> 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.
