Enum PinnedCap 

pub enum PinnedCap {
    Data {
        desc: DataDesc,
    },
    Image {
        content_hash: [u8; 32],
    },
}

Pinned slot content. Only content-addressed cap kinds can be pinned (Data or Image). Cap::Data bytes are inlined in the Image; a future optimisation can add a hash-only variant for content that lives in σ.data_payloads.

Variants

Data

Pinned Cap::Data as a page-granular DataDesc over the Image arena. All-zero pages are elided.

Fields

desc: DataDesc

Image

Pinned Cap::Image by content hash. Cap::Image is itself content-addressed; inlining a whole sub-Image makes less sense than for Data.

Fields

content_hash: [u8; 32]

Trait Implementations

impl Clone for PinnedCap

fn clone(&self) -> PinnedCap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PinnedCap

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

Formats the value using the given formatter.

impl Decode for PinnedCap

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 PinnedCap

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 PinnedCap

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 PinnedCap

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