Struct ExplainStatement 

pub struct ExplainStatement {
    pub analyze: bool,
    pub inner: Box<SelectStatement>,
    pub suggest: bool,
    pub costs_off: bool,
}

Fields

analyze: bool

inner: Box<SelectStatement>

suggest: bool

v6.8.3 — EXPLAIN (SUGGEST) <SELECT> enables the index advisor pass: after the regular plan tree, the engine emits one suggestion line per column referenced in the query’s WHERE / JOIN that has no covering index on the owning table.

costs_off: bool

v7.37.7 — EXPLAIN (COSTS OFF) <SELECT> strips wall-clock elapsed=…us annotations from the Total line (and any future cost-bearing lines). PG-standard option used by regression suites and diff-friendly EXPLAIN output. When true, takes precedence over the per-session SPG_TEST_EXPLAIN_NO_COSTS GUC.

Trait Implementations

impl Clone for ExplainStatement

fn clone(&self) -> ExplainStatement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExplainStatement

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

Formats the value using the given formatter.

impl PartialEq for ExplainStatement

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