Available on crate feature bulk-load-profile only.

Detailed timing statistics for an experimental raw-bulk direct packet writer.

These counters are intended to compare an experimental bulk-only packet writer against the framed sink path. They remain zero when the framed path is used.

Fields

calls: u64

Number of TDS packets passed to the direct packet writer.

payload_bytes: u64

Payload bytes passed to the direct packet writer, excluding headers.

header_bytes: u64

Header bytes written by the direct packet writer.

max_payload_bytes: usize

Largest payload passed to the direct packet writer.

final_calls: u64

Number of final EndOfMessage packets passed to the direct packet writer.

final_payload_bytes: u64

Payload bytes in final EndOfMessage packets.

final_header_bytes: u64

Header bytes in final EndOfMessage packets.

Trait Implementations

impl Clone for BulkLoadDirectPacketWriteStats

fn clone(&self) -> BulkLoadDirectPacketWriteStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BulkLoadDirectPacketWriteStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BulkLoadDirectPacketWriteStats

fn default() -> BulkLoadDirectPacketWriteStats

Returns the “default value” for a type.

impl PartialEq for BulkLoadDirectPacketWriteStats

fn eq(&self, other: &BulkLoadDirectPacketWriteStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
