Add rust-bundle, a single staticlib crate that depends on both libchat and rln as rlibs. This ensures rustc links Rust std exactly once, eliminating duplicate symbol errors on all platforms. Nim targets link against liblogos_chat_bundle.a; Nix uses a bundleDrv instead of separate libchat and rln derivations.

Logos Chat
A privacy focused decentralized messaging SDK, built on the Logos Stack. Logos Chat provides permission-less, censorship-resistant communication for humans and clankers.
Quick Start
Prerequisites
Build
# Initialize submodules and dependencies
make update
# Build all targets (examples + shared library)
make all
# Run tests
make tests
Quick Tasks
Here are common tasks to get up and running. See examples/ for full examples, including pingpong.nim which demonstrates a full two-client conversation.
Initialize Client
let waku = initWakuClient(DefaultConfig())
var client = newClient(waku).get()
...
...
client.start()
Create Introduction Bundle
Introductions are single use key-bundles required by Senders to initiate a conversation. Recipients must generate them before anyone can contact them. IntroBundles contain no secrets and can be published, or transmitted over over other channels.
...
# IntroBundles are sent to other clients Out-of-Band to establish a conversation.
let intro_bundle = client.createIntroBundle()
...
Create 1:1 Chat
Once a Sender has retrieved a bundle then they can create a conversation. All conversations must have an initial message.
...
let initial_content = @[1,2,3]
# This intro_bundle must come from another client
let convo_id = await client.newPrivateConversation( intro_bundle, initial_content )
...
Receive Message
Receiving a message is accomplished by registering a callback.
...
client.onNewMessage(proc( convo: Conversation, msg: ReceivedMessage ) {.async.} =
echo convo.id(), msg.content
)
...
Send Message
...
let content = @[1,2,3]
let convo = client.getConversation( convo_id )
await client.sendMessage( content )
...

C Bindings
A shared library with C bindings is available:
make liblogoschat
This produces build/liblogoschat.{dylib,so,dll}. See library/liblogoschat.h and examples/cbindings/ for usage.
