Struct ShortRepresentation 

#[non_exhaustive]
pub struct ShortRepresentation {
    pub description: String,
    pub subqueries: HashMap<String, i32>,
    /* private fields */
}

Condensed representation of a node and its subtree. Only present for SCALAR PlanNode(s).

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.

description: String

A string representation of the expression subtree rooted at this node.

subqueries: HashMap<String, i32>

A mapping of (subquery variable name) -> (subquery node id) for cases where the description string of this node references a SCALAR subquery contained in the expression subtree rooted at this node. The referenced SCALAR subquery may not necessarily be a direct child of this node.

Implementations

impl ShortRepresentation

pub fn new() -> Self

Creates a new default instance.

pub fn set_description<T: Into<String>>(self, v: T) -> Self

Sets the value of description.

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

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<i32>,

Sets the value of subqueries.

Trait Implementations

impl Clone for ShortRepresentation

fn clone(&self) -> ShortRepresentation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShortRepresentation

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

Formats the value using the given formatter.

impl Default for ShortRepresentation

fn default() -> ShortRepresentation

Returns the “default value” for a type.

impl Message for ShortRepresentation

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ShortRepresentation

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