Struct PlanNode

pub struct PlanNode<T: NodeType> {
    pub typ: T,
    pub children: Vec<PlanNodeOrGroup<T>>,
    pub predicates: Vec<ArcPredNode<T>>,
}

Fields

typ: T

A generic plan node type

children: Vec<PlanNodeOrGroup<T>>

Child plan nodes, which may be materialized or placeholder group IDs based on how this node was initialized

predicates: Vec<ArcPredNode<T>>

Predicate nodes, which are always materialized

Implementations

impl<T: NodeType> PlanNode<T>

pub fn child(&self, idx: usize) -> PlanNodeOrGroup<T>

pub fn child_rel(&self, idx: usize) -> ArcPlanNode<T>

pub fn predicate(&self, idx: usize) -> ArcPredNode<T>

Trait Implementations

impl<T: Clone + NodeType> Clone for PlanNode<T>

fn clone(&self) -> PlanNode<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + NodeType> Debug for PlanNode<T>

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

Formats the value using the given formatter.

impl<T: NodeType> Display for PlanNode<T>

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

Formats the value using the given formatter.

impl<T: NodeType> From<PlanNode<T>> for PlanNodeOrGroup<T>

fn from(value: PlanNode<T>) -> Self

Converts to this type from the input type.

impl<T: Hash + NodeType> Hash for PlanNode<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq + NodeType> PartialEq for PlanNode<T>

fn eq(&self, other: &PlanNode<T>) -> 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.
