MemoryStats

Python allocation measurements in a line's memory field. For RAM, see ProcessMemoryStats.

dataclass linescope.model.MemoryStats[source]

Describe allocation measurements in bytes, separate from process RAM.

The shared collector measures net retained Python allocations by allocation site. It leaves allocation peaks unavailable; process RSS belongs to ProcessMemoryStats. Custom collectors can supply their own allocation measurements, keeping missing values unknown.

Attributes

delta_bytes : int | None Signed allocation change in bytes; None means unavailable. peak_bytes : int | None Highest measured allocated bytes; None means unavailable.
