Struct Correlation 

pub struct Correlation {
    pub parent_field: Vec<Box<str>>,
    pub child_field: Vec<Box<str>>,
}

The join key pair (Correlation, ast.ts:245-248). parent_field[i] on the parent correlates with child_field[i] on the child; both non-empty, same length.

Fields

parent_field: Vec<Box<str>>

Column name(s) on the parent table.

child_field: Vec<Box<str>>

Column name(s) on the child (subquery) table.

Trait Implementations

impl Clone for Correlation

fn clone(&self) -> Correlation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Correlation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Correlation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Correlation

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

impl Serialize for Correlation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
