Struct CounterSnapshot 

pub struct CounterSnapshot {
    pub queries: u64,
    pub writes: u64,
    pub write_rows: u64,
    pub errors_by_code: BTreeMap<String, u64>,
    pub admin_ops: u64,

}

Snapshot of engine-internal counters returned by Engine::counters.

Public key set is owned by dev/design/lifecycle.md § Public key set and locked by AC-004a. Reading a snapshot is non-perturbing per AC-004c. The 0.6.0 surface exposes exactly these seven fields.

Fields

queries: u64

writes: u64

write_rows: u64

errors_by_code: BTreeMap<String, u64>

admin_ops: u64

cache_hit: u64

Trait Implementations

impl Clone for CounterSnapshot

fn clone(&self) -> CounterSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CounterSnapshot

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

Formats the value using the given formatter.

impl Default for CounterSnapshot

fn default() -> CounterSnapshot

Returns the “default value” for a type.

impl PartialEq for CounterSnapshot

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