Struct StagingStats 

pub struct StagingStats {
    pub allocations: u64,
    pub staged_transfers: u64,
    pub direct_transfers: u64,
    pub bytes_uploaded: u64,
    pub bytes_downloaded: u64,
}

Counters describing how a StagingBuffer has been used.

Chiefly useful for asserting in tests (and in production tracing) that the buffer really is being reused rather than silently re-pinned every call — the entire point of the type. A healthy hot loop shows allocations == 1 and a large staged_transfers.

Fields

allocations: u64

Number of times a pinned host allocation was performed (initial + grows).

staged_transfers: u64

Transfers that were staged through the pinned buffer.

direct_transfers: u64

Transfers routed straight to the driver’s pageable path because they exceeded StagingBuffer::auto_stage_max_bytes.

bytes_uploaded: u64

Total bytes uploaded host→device through this buffer (both paths).

bytes_downloaded: u64

Total bytes downloaded device→host through this buffer (both paths).
