A GroupV2 conversation carries a shared name and description in its MLS group context, set at creation and delivered to every joiner in the welcome. The threaded client could create groups but neither set that metadata nor read it back, leaving both fields unreachable through the client API. create_group_conversation now takes a GroupMetadata and creates the group with its name and description via create_group_convo_v2; both fields may be empty for an unnamed group. A new group_metadata getter reads a group's metadata back, erroring for a direct conversation or a legacy group that carries none. GroupMetadata is a distinct input type, kept separate from the ConvoMetadata a conversation reports back so the two can evolve independently; both are re-exported from the crate root and from logos-generic-chat.
libchat
Supporting library for Logos-chat
Example app
bin/chat-cli is an end-to-end encrypted CLI chat app
built on this library. By default it uses logos-delivery
(Waku-based) as the transport so two users anywhere in the world can chat by
sharing an intro bundle. A local file transport is also bundled in; pick at
runtime with --transport <logos-delivery|file>.
# Build logos-delivery with Nix
nix build .#logos-delivery
# Build chat-cli with Cargo
LOGOS_DELIVERY_LIB_DIR=./result/lib cargo build --release -p chat-cli
# Run binary (defaults to --transport logos-delivery)
./target/release/chat-cli --name alice
See bin/chat-cli/README.md for full build,
run, and test instructions.
