Changelog

All notable changes to Vox are documented here.

[Unreleased]

Changed

  • Remove the implicit From<DriverCaller> for () conversion. Use NoopCaller when you need to retain root connection liveness without exposing root RPC methods.

  • No entries yet.

[7.0.0] - 2026-03-02

Breaking

  • Service trait implementations no longer receive &Context; methods now either:
    • return owned values directly, or
    • receive call: impl vox::Call<T, E> for explicit 'vox borrowed response paths.
  • Generated service trait naming and generated descriptor access changed:
    • Generated service traits are still named {Service}.
    • Codegen inputs moved from *_service_detail() to *_service_descriptor().
  • Client construction and session setup were updated:
    • ConnectionHandle is no longer a Caller; clients are created from driver.caller().
    • Session bootstrapping moved from accept_framed / initiate_framed to session::acceptor / session::initiator with .establish().

Changed

  • Client return types were standardized:
    • Owned returns remain direct values (e.g. T).
    • Borrowed 'vox returns now return SelfRef<T>.
    • Generated Rust clients do not expose response metadata in return types.
  • Channel APIs now use const-generic credit: Tx<T, N> / Rx<T, N>, with default credit N = 16.
  • SHM hosting moved to a smaller, lower-level v7 API surface:
    • ShmHost, bootstrap, driver, AddPeerOptions, MultiPeerHostDriver are no longer part of the API surface used for orchestration.
    • New primitives are vox_shm::segment::{Segment, SegmentConfig} and related methods (reserve_peer, claim_peer, attach_peer, detach_peer, recover_crashed_peer).
    • Orchestration helpers are now focused and explicit via vox_shm::ShmLink, vox_shm::host::HostHub, and vox_shm::host ticket/link helpers.

Added

  • Explicit v7 virtual-connection model in session API:
    • Root sessions are established via session::{initiator,acceptor}.establish().
    • Virtual connections are opened through SessionHandle::open_connection(...).
    • on_connection(...) hooks are now opt-in; inbound virtual opens are rejected by default when not configured.
  • Added migration guidance for borrowed-response methods:
    • Use call.ok(...), call.err(...), and call.reply(...) on call: impl Call<...> for explicit borrow-based replies.

Removed

  • client.method(...).with_metadata(...) does not have a generated call-builder equivalent in v7; use lower-level request construction when metadata injection is required.
