Functions

func BindValueTrace added in v1.18.0 

func BindValueTrace(val any, trace *cell.Trace) any

BindValueTrace returns val ready to live on a stack or in c7 bound to the given cell trace: slices and builders are copied with the trace attached (snapshotting their cursor), tuples are rebound recursively and typed nil pointers collapse to plain nil, except a null slice reference whose slice tag is observable in legacy TVM behavior. Values that already carry the trace are returned as-is. A nil trace returns val unchanged.

func IsHandledException added in v1.18.0 

func IsHandledException(err error) bool

IsHandledException is an allocation-free errors.As for HandledException.

func IsSuccessExitCode 

func IsSuccessExitCode(code int64) bool
