Struct FloorPrefixDecoder 

pub struct FloorPrefixDecoder {
    pub key: KeyId,
    pub first: Slot,
    /* private fields */
}

Incremental clear-prefix decoder. Supply one bounded copy piece at a time.

Fields

key: KeyId

Store key sealing the floor stream.

first: Slot

First kept slot; guides key discovery until the floor authenticates.

Implementations

impl FloorPrefixDecoder

pub const HEADER_LENGTH: usize = 31

Exact initial routing length, before copy pieces.

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

Read exactly the initial routing and bounded copy count.

pub fn remaining(&self) -> u32

Number of copy pieces still needed, before the encrypted body begins.

pub fn copy_length(&self, bytes: &[u8]) -> Result<usize, Error>

Bound one copy’s slot and length fields before allocating its body.

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

Decode one complete original slot, keeping its signed bytes intact.

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

Refuse a prefix missing any declared copy.
