Summary
impl_tuple!macro that caused test failuresChanges
Bug Fix: Null Pointer Dereference in
impl_tuple!The
impl_tuple!macro inhdf5-types/src/h5type.rswas using undefined behavior by dereferencing a null pointer to compute field offsets:This caused tests to fail with "null pointer dereference occurred" on recent Rust versions. Fixed by replacing with
std::mem::offset_of!which is safe and stable since Rust 1.77.Warning Fixes
windows_dllcfg registration, lifetime elision warnings inDynValueRuntimeErrorstruct, registered all custom cfg valuesdocrstypo, added explicit lifetimes, suppressed intentional function pointer comparison warningMSRV Update
Updated minimum supported Rust version from 1.64.0 to 1.80.0 to enable
rustc-check-cfgsupport for proper cfg validation.Test plan
