This was particularly problematic on embedded aarch64 devices with constrained memory. Struct Alignment Optimizations: - Optimized CallContext field ordering to reduce padding (~8 bytes saved per instance) - Eliminated SessionData wrapper in Session struct for better cache locality - Reordered PendingSessionInfo fields to minimize internal padding - Improved memory alignment for frequently allocated structures Impact: - Eliminates proportional memory growth with Firebolt API calls - Reduces per-EventListener memory overhead by 8+ bytes - Improves cache locality and reduces heap fragmentation - Critical for embedded deployment on memory-constrained devices All tests pass (27 session-related tests), no functional regressions. Validated with clippy and comprehensive test suite. --- core/main/src/state/session_state.rs | 25 +++++++++------------ core/sdk/src/api/gateway/rpc_gateway_api.rs | 16 ++++++++----- 2 files changed, 22 insertions(+), 19 deletions(-) diff --git a/core/main/src/state/session_state.rs b/core/main/src/state/session_state.rs index e15abb2a5..b016c13f0 100644 --- a/core/main/src/state/session_state.rs +++ b/core/main/src/state/session_state.rs @@ -31,22 +31,18 @@ use ripple_sdk::{ utils::error::RippleError, }; -#[derive(Debug, Clone)] -pub struct SessionData { -
