Struct FloorFrames 

pub struct FloorFrames { /* private fields */ }

Incremental floor frame codec; no bound is imposed on the complete stream.

Implementations

impl FloorFrames

pub fn start(header: FloorHeader) -> Result<(Self, Vec<u8>), Error>

Begin encoding with the validated floor header.

pub fn decode_header(bytes: &[u8], first: Slot) -> Result<Self, Error>

Start decoding from its initial header frame, checking the clear prefix.

pub fn header(&self) -> &FloorHeader

Unauthenticated header; verify the floor before granting authority.

pub fn announcement(&mut self, slot: &OriginalSlot) -> Result<Vec<u8>, Error>

Encode the next original announcement, checking header order.

pub fn end(&mut self) -> Result<Vec<u8>, Error>

Encode the required end frame after all announcements.

pub fn frame(&mut self, bytes: &[u8]) -> Result<Option<OriginalSlot>, Error>

Decode one announcement or the end marker, preserving exact evidence.

pub fn finish(&self) -> Result<(), Error>

Require the end marker before accepting the stream.
