Implementations

impl Subquery

pub fn try_from_expr(plan: &Expr) -> Result<&Subquery>

pub fn with_plan(&self, plan: Arc<LogicalPlan>) -> Subquery

Trait Implementations

impl Clone for Subquery

fn clone(&self) -> Subquery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Subquery

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

Formats the value using the given formatter.

impl Hash for Subquery

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 NormalizeEq for Subquery

fn normalize_eq(&self, other: &Self) -> bool

impl Normalizeable for Subquery

fn can_normalize(&self) -> bool

impl PartialEq for Subquery

fn eq(&self, other: &Subquery) -> 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 PartialOrd for Subquery

fn partial_cmp(&self, other: &Subquery) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
