Struct Statistic 

pub struct Statistic {
    pub qname: QualifiedName,
    pub target: QualifiedName,
    pub kinds: StatisticKinds,
    pub columns: Vec<StatisticColumn>,
    pub statistics_target: Option<i32>,
    pub owner: Option<Identifier>,
    pub comment: Option<String>,
}

Declarative model of a Postgres CREATE STATISTICS object.

Fields

qname: QualifiedName

Schema-qualified statistic name (explicit names required).

target: QualifiedName

The target table whose columns are correlated.

kinds: StatisticKinds

Which kinds are enabled. At least one must be true (canon enforces).

columns: Vec<StatisticColumn>

Column / expression list. Sorted by canon; deduped.

statistics_target: Option<i32>

ALTER STATISTICS s SET STATISTICS n — analyze target. None = unmanaged / use PG default (-1).

owner: Option<Identifier>

Object owner. None = unmanaged (v0.3.1 lenient pattern).

comment: Option<String>

Optional COMMENT ON STATISTICS.

Trait Implementations

impl Clone for Statistic

fn clone(&self) -> Statistic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Statistic

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Statistic

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Statistic

impl PartialEq for Statistic

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

impl Serialize for Statistic

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
