Struct CacheKey 

pub struct CacheKey {
    pub subquery_repr: String,
    pub outer_values: Vec<Value>,
}

Cache key — the subquery’s textual identity plus the outer row’s value tuple. Two scalar-subquery node positions with identical Display text are treated as the same subquery for caching purposes (sound: equal Display → equal AST).

Fields

subquery_repr: String

outer_values: Vec<Value>

Trait Implementations

impl Clone for CacheKey

fn clone(&self) -> CacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheKey

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

Formats the value using the given formatter.

impl PartialEq for CacheKey

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