Struct UsageSnapshot

pub struct UsageSnapshot {
    pub elapsed: Duration,
    pub bytes_read: u64,
    pub bytes_written: u64,
    pub keys_values_fetched: u64,
    pub call_get: u64,
    pub call_get_range: u64,
    pub call_set: u64,
    pub call_clear: u64,
    pub call_clear_range: u64,
    pub call_atomic_op: u64,
}

A copy of the counters of a single transaction attempt, taken by AttemptUsage::snapshot or Transaction::attempt_usage.

Every byte count is a client-side estimate, see the module documentation.

Fields

elapsed: Duration

Time elapsed since the attempt started.

bytes_read: u64

Bytes read: for each resolved read, the key(s) requested plus the key-values returned.

bytes_written: u64

Bytes written: keys, values and mutation parameters handed to the client. For clear_range only the two boundary keys are counted, not the volume of data the range deletes.

keys_values_fetched: u64

Number of key-values returned by resolved reads.

call_get: u64

Number of get and get_key calls resolved.

call_get_range: u64

Number of get_range batches resolved. A single get_ranges stream counts once per underlying FoundationDB batch, not once per stream.

call_set: u64

Number of set calls.

call_clear: u64

Number of clear calls.

call_clear_range: u64

Number of clear_range calls.

call_atomic_op: u64

Number of atomic_op calls.

Trait Implementations

impl Clone for UsageSnapshot

fn clone(&self) -> UsageSnapshot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UsageSnapshot

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

Formats the value using the given formatter.

impl Default for UsageSnapshot

fn default() -> UsageSnapshot

Returns the “default value” for a type.

impl PartialEq for UsageSnapshot

fn eq(&self, other: &UsageSnapshot) -> 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.
