Struct RopeStep

Source

pub struct RopeStep {
    pub snapshot: EntropySnapshot,
    pub counter: u64,
}

Expand description

Metadata from a single ratchet step, embedded in messages so the receiver can perform the same derivation.

Contains the entropy snapshot (the unrepeatable moment) and the message counter (for ordering). Both are needed to reproduce the exact strand evolution on the receiving side.

Fields§

§snapshot: EntropySnapshot

The entropy snapshot captured during this step.

§counter: u64

The message counter at this step.

Implementations§

Source §

impl RopeStep

Source

pub const BYTES: usize

Serialized size: 8 (counter) + 48 (snapshot) = 56 bytes.

Source

pub fn to_bytes(&self) -> Vec<u8> ⓘ

Serialize the step metadata for transmission.

Source

pub fn from_bytes(data: &[u8]) -> Result<Self>

Deserialize step metadata from received bytes.
