Struct SuperblockSlot 

pub struct SuperblockSlot {
    pub position_pages: u32,
    pub size_bytes: u32,
}

One of the four superblock copies.

Fields

position_pages: u32

Position in 256-byte units. Multiply by 256 to get the byte offset.

size_bytes: u32

Size in bytes of the superblock body at that position.

Implementations

impl SuperblockSlot

pub fn is_empty(&self) -> bool

True when this slot is not usable as a superblock pointer.

Either field being zero disqualifies the slot: position=0 points at the file header (1A 00 LSIG, not a superblock), and size=0 means there is nothing to read. Empirically (comparedbs.ntf and other fresh / never-instantiated HCL templates) Domino writes position=0 with a nonzero size on uninitialized slots, so the stricter both-must-be-nonzero rule is required to filter them out.

pub fn byte_offset(&self) -> Option<u64>

Byte offset of this superblock body. Returns None for an empty slot so consumers do not chase zero offsets.

Trait Implementations

impl Clone for SuperblockSlot

fn clone(&self) -> SuperblockSlot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SuperblockSlot

impl Debug for SuperblockSlot

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

Formats the value using the given formatter.

impl Eq for SuperblockSlot

impl PartialEq for SuperblockSlot

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