Mojo struct
NullTrace
struct NullTrace
Zero-sized no-op trace buffer.
store is pass; the struct has no fields so it contributes 0
kernel-arg bytes when passed as an argument. Combined with a
comptime if enable_trace: guard at every call site, the no-trace
path emits zero PTX for instrumentation.

comptime members
device_type
comptime device_type = NullTrace
Device-side type alias. NullTrace is trivially device-passable.
Methods
__init__
def __init__() -> Self
Constructs a zero-sized no-op trace buffer.
store
def store(self, offset: Int, val: UInt64)
No-op store. The body compiles away entirely.
Args:
get_type_name
static def get_type_name() -> String
Returns the type name for runtime diagnostics.
Returns:
String: Always "NullTrace".
