Struct MainFrame 

pub struct MainFrame<'a> { /* private fields */ }

Read-only view of an active Instance’s MainFrame cnode.

Implementations

impl<'a> MainFrame<'a>

pub fn new( cnode: &'a CNodeCap, pinned: &'a [SlotIdx], cache: &'a CacheDirectory, ) -> Self

pub fn size_log(&self) -> u8

Cnode size as log2(slots).

pub fn is_pinned(&self, idx: SlotIdx) -> bool

True if idx is declared pinned by the Image.

pub fn get(&self, idx: SlotIdx) -> Option<CapHashOrRef>

Read a single root-cnode slot target.

pub fn resolve(&self, path: &SlotPath) -> Result<Option<CapHashOrRef>, VmError>

Resolve a SlotPath against this MainFrame. Walks nested Cap::CNode slots via the cache; returns the cap target at the path’s terminal slot (or None if the slot is empty).

Error: if any intermediate step fails to land on a Cap::CNode or hits an empty slot, returns VmError::{SlotKindMismatch, SlotEmpty}.
