Struct Frame 

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

A completed frame produced by the guest: a sequence of opcodes plus arena access.

Frame is the transport seam: both the shared-memory ring (Host) and network batch decoders produce frame views, so consumers such as RenderTree::apply_frame work identically regardless of origin.

Implementations

impl<'a> Frame<'a>

pub fn from_parts( slots: &'a [u8], arena: &'a [u8], start: usize, end: usize, ) -> Self

Construct a frame view over contiguous 16-byte opcode slots plus an arena region (start/end are byte offsets into slots).

Used by transport backends to produce Frame views over their own buffers; Host builds these internally from the ring.

pub fn opcodes(&self) -> FrameIter<'a>

Iterate the opcodes in this frame, in order.

pub fn len(&self) -> usize

Number of opcodes in the frame.

pub fn is_empty(&self) -> bool

pub fn arena_get(&self, offset: u32) -> Result<&'a [u8], ArenaError>

Read an arena entry by offset (see Guest::alloc / Guest::alloc_str).

pub fn arena_str(&self, offset: u32) -> Result<&'a str, ArenaError>

Read an arena string by offset.

pub fn arena(&self) -> &'a [u8]

The full arena region (for transport serialization of arena deltas).
