Struct Contacts 

pub struct Contacts { /* private fields */ }

A client-local contact list. It lives on the device and is never sent to the server, so the server never learns a user’s contact graph — the metadata-privacy choice for an end-to-end-encrypted messenger. Serialize with to_bytes to persist it across restarts; a user’s contacts do not sync across their devices without doing that deliberately.

Implementations

impl Contacts

pub fn new() -> Contacts

An empty contact list.

pub fn add(&mut self, contact: Contact)

Add a contact, ignoring a duplicate (by address).

pub fn remove(&mut self, handle: &str)

Remove every contact with this handle.

pub fn get(&self, handle: &str) -> Option<&Contact>

The contact with this handle, if any.

pub fn all(&self) -> &[Contact]

Every contact.

pub fn to_bytes(&self) -> Vec<u8>

Serialize the list to bytes, to persist on the device.

pub fn from_bytes(bytes: &[u8]) -> Option<Contacts>

Reconstruct a list from to_bytes; None on any malformation.
