Struct TableStats 

pub struct TableStats {
    pub name: String,
    pub n_pages: u64,
    pub n_rows: u64,
    pub source: StatsSource,
}

Statistics about a table, used for cost estimation.

Fields

name: String

Table name.

n_pages: u64

Number of B-tree pages occupied by the table.

n_rows: u64

Estimated number of rows (from ANALYZE or heuristic).

source: StatsSource

Source of these statistics.

Trait Implementations

impl Clone for TableStats

fn clone(&self) -> TableStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableStats

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

Formats the value using the given formatter.

impl Eq for TableStats

impl From<&TableStats> for TableStatsSummary

fn from(ts: &TableStats) -> Self

Converts to this type from the input type.

impl PartialEq for TableStats

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