master

BC Breaks

• Schema::Context now requires Clone bound for ability to have a "fresh" context value each time a new GraphQL operation is started in a WebSocket connection. (#1369)

  COMPATIBILITY: Previously, it was Arced inside, sharing the same context value across all GraphQL operations of a WebSocket connection. To preserve the previous behavior, the Schema::Context type should be either wrapped into Arc or made Arc-based internally.

• Replaced ConnectionConfig::keep_alive_interval option with ConnectionConfig::keep_alive one as KeepAliveConfig. (#1367)
• Made WebSocket connection closed once ConnectionConfig::keep_alive::timeout is reached in graphql-transport-ws GraphQL over WebSocket Protocol. (#1367)

  COMPATIBILITY: Previously, a WebSocket connection was kept alive, even when clients do not respond to server's Pong messages at all. To preserve the previous behavior, the ConnectionConfig::keep_alive::timeout should be set to Duration:::ZERO.

Added

• ConnectionConfig::panic_handler field and ConnectionConfig::with_panic_handler() method allowing to specify PanicHandler for panics happened during execution of GraphQL operations. (#1371)

Changed

• Merged graphql_transport_ws::NextPayload and graphql_ws::DataPayload into a single struct. (#1371)

Fixed

• Inability to re-subscribe with the same operation id after subscription was completed by server. (#1368)
