pub enum PageSlot {
Empty,
Loaded(PageRef),
Missing(CapHash),
}Expand description
Sparse representation of a paged DataCap’s pages. Empty is the
canonical zero page; Loaded holds a refcounted byte slab;
Missing records the page’s content hash so a host callback can
later resolve it (V1: never observed — we always pre-publish).

Source§fn is_ssz_fixed_len() -> bool
fn is_ssz_fixed_len() -> bool
true iff this type is fixed-length (no variable-length fields).Source§fn ssz_fixed_len() -> usize
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).Source§fn ssz_bytes_len(&self) -> usize
fn ssz_bytes_len(&self) -> usize
Total size of
self when serialized.Source§fn ssz_append(&self, buf: &mut Vec<u8>)
fn ssz_append(&self, buf: &mut Vec<u8>)
Append the encoding of
self to buf.Source§fn is_basic_type() -> bool
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).Source§impl HashTreeRoot for PageSlot
