Struct ExecutionSummaryCounts 

pub struct ExecutionSummaryCounts {
    pub iops: usize,
    pub requests: usize,
    pub bytes_read: usize,

}

Fields

iops: usize

The number of I/O operations performed

requests: usize

The number of requests made to the storage layer (may be larger or smaller than iops depending on coalescing configuration)

bytes_read: usize

The number of bytes read during the execution of the plan

indices_loaded: usize

The number of top-level indices loaded

parts_loaded: usize

The number of index partitions loaded

index_comparisons: usize

The number of index comparisons performed (the exact meaning depends on the index type)

all_counts: HashMap<String, usize>

Additional metrics for more detailed statistics. These are subject to change in the future and should only be used for debugging purposes.

Trait Implementations

impl Clone for ExecutionSummaryCounts

fn clone(&self) -> ExecutionSummaryCounts

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionSummaryCounts

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

Formats the value using the given formatter.

impl Default for ExecutionSummaryCounts

fn default() -> ExecutionSummaryCounts

Returns the “default value” for a type.

impl PartialEq for ExecutionSummaryCounts

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