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

Trait Implementations

impl Clone for Subquery

fn clone(&self) -> Subquery

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl From<PyScalarSubquery> for Subquery

fn from(subquery: PyScalarSubquery) -> Self

Converts to this type from the input type.

impl From<PySubquery> for Subquery

fn from(subquery: PySubquery) -> Self

Converts to this type from the input type.

impl From<Subquery> for PyScalarSubquery

fn from(subquery: Subquery) -> PyScalarSubquery

Converts to this type from the input type.

impl From<Subquery> for PySubquery

fn from(subquery: Subquery) -> PySubquery

Converts to this type from the input type.

impl Hash for Subquery

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

where __H: Hasher,

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 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.
