Struct ResultSetStats 

#[non_exhaustive]
pub struct ResultSetStats {
    pub query_plan: Option<QueryPlan>,
    pub query_stats: Option<Struct>,
    pub row_count: Option<RowCount>,
    /* private fields */
}

Additional statistics about a ResultSet or PartialResultSet.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

query_plan: Option<QueryPlan>

QueryPlan for the query associated with this result.

query_stats: Option<Struct>

Aggregated statistics from the execution of the query. Only present when the query is profiled. For example, a query could return the statistics as follows:

{
  "rows_returned": "3",
  "elapsed_time": "1.22 secs",
  "cpu_time": "1.19 secs"
}

row_count: Option<RowCount>

The number of rows modified by the DML statement.

Implementations

impl ResultSetStats

pub fn new() -> Self

Creates a new default instance.

pub fn set_query_plan<T>(self, v: T) -> Self

where T: Into<QueryPlan>,

Sets the value of query_plan.

pub fn set_or_clear_query_plan<T>(self, v: Option<T>) -> Self

where T: Into<QueryPlan>,

Sets or clears the value of query_plan.

pub fn set_query_stats<T>(self, v: T) -> Self

where T: Into<Struct>,

Sets the value of query_stats.

pub fn set_or_clear_query_stats<T>(self, v: Option<T>) -> Self

where T: Into<Struct>,

Sets or clears the value of query_stats.

pub fn set_row_count<T: Into<Option<RowCount>>>(self, v: T) -> Self

Sets the value of row_count.

Note that all the setters affecting row_count are mutually exclusive.

pub fn row_count_exact(&self) -> Option<&i64>

The value of row_count if it holds a RowCountExact, None if the field is not set or holds a different branch.

pub fn set_row_count_exact<T: Into<i64>>(self, v: T) -> Self

Sets the value of row_count to hold a RowCountExact.

Note that all the setters affecting row_count are mutually exclusive.

pub fn row_count_lower_bound(&self) -> Option<&i64>

The value of row_count if it holds a RowCountLowerBound, None if the field is not set or holds a different branch.

pub fn set_row_count_lower_bound<T: Into<i64>>(self, v: T) -> Self

Sets the value of row_count to hold a RowCountLowerBound.

Note that all the setters affecting row_count are mutually exclusive.

Trait Implementations

impl Clone for ResultSetStats

fn clone(&self) -> ResultSetStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResultSetStats

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

Formats the value using the given formatter.

impl Default for ResultSetStats

fn default() -> ResultSetStats

Returns the “default value” for a type.

impl Message for ResultSetStats

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ResultSetStats

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