Struct QueryPlan 

#[non_exhaustive]
pub struct QueryPlan {
    pub plan_nodes: Vec<PlanNode>,
    pub query_advice: Option<QueryAdvisorResult>,
    /* private fields */
}

Contains an ordered list of nodes appearing in the query plan.

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.

plan_nodes: Vec<PlanNode>

The nodes in the query plan. Plan nodes are returned in pre-order starting with the plan root. Each PlanNode’s id corresponds to its index in plan_nodes.

query_advice: Option<QueryAdvisorResult>

Optional. The advise/recommendations for a query. Currently this field will be serving index recommendations for a query.

Implementations

impl QueryPlan

pub fn new() -> Self

Creates a new default instance.

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

where T: IntoIterator<Item = V>, V: Into<PlanNode>,

Sets the value of plan_nodes.

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

where T: Into<QueryAdvisorResult>,

Sets the value of query_advice.

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

where T: Into<QueryAdvisorResult>,

Sets or clears the value of query_advice.

Trait Implementations

impl Clone for QueryPlan

fn clone(&self) -> QueryPlan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryPlan

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

Formats the value using the given formatter.

impl Default for QueryPlan

fn default() -> QueryPlan

Returns the “default value” for a type.

impl Message for QueryPlan

fn typename() -> &'static str

The typename of this message.

impl PartialEq for QueryPlan

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