Struct InitialDataCap 

pub struct InitialDataCap {
    pub content: Vec<u8>,
    pub size: u64,
}

Initial Cap::Data content for a non-pinned mutable slot. Used at standalone (root) Instance bootstrap to seed the cnode. A parented Instance receives its slots from the spawner and ignores this field.

Fields

content: Vec<u8>

Initial bytes. May be empty for zero-filled regions like stack and heap.

size: u64

Logical size of the cap. size may be larger than content.len(); trailing bytes are zero-filled when the cap is mapped.

Trait Implementations

impl Clone for InitialDataCap

fn clone(&self) -> InitialDataCap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitialDataCap

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

Formats the value using the given formatter.

impl Decode for InitialDataCap

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 Default for InitialDataCap

fn default() -> InitialDataCap

Returns the “default value” for a type.

impl Encode for InitialDataCap

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 InitialDataCap

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 InitialDataCap

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