Struct tcn::TemporaryContactKey

pub struct TemporaryContactKey { /* fields omitted */ }

A ratcheting key used to derive temporary contact numbers.

Methods

impl TemporaryContactKey

pub fn index(&self) -> u16

The current ratchet index.

pub fn temporary_contact_number(&self) -> TemporaryContactNumber

Compute the temporary contact number derived from this key.

pub fn ratchet(self) -> Option<TemporaryContactKey>

Ratchet the key forward, producing a new key for a new temporary contact number.

Returns

• Some(new_key) if the current ratchet index is less than u16::MAX;
• None if the current ratchet index is u16::MAX, signaling that the report authorization key should be rotated.

impl TemporaryContactKey

pub fn read<R: Read>(reader: R) -> Result<TemporaryContactKey, Error>

Try to read a TemporaryContactKey from a generic io::Reader.

pub fn write<W: Write>(&self, writer: W) -> Result<(), Error>

Try to write a TemporaryContactKey into a generic io::Writeer.
