Struct proof_of_sql::sql::postprocessing::SliceExpr

pub struct SliceExpr<S: Scalar> { /* private fields */ }

A SliceExpr represents a slice of a LazyFrame.

Implementations

impl<S: Scalar> SliceExpr<S>

pub fn new(number_rows: Option<u64>, offset_value: Option<i64>) -> Self

Create a new SliceExpr with the given number_rows and offset.

Trait Implementations

impl<S: Clone + Scalar> Clone for SliceExpr<S>

fn clone(&self) -> SliceExpr<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug + Scalar> Debug for SliceExpr<S>

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

Formats the value using the given formatter.

impl<'de, S: Scalar> Deserialize<'de> for SliceExpr<S>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<S: PartialEq + Scalar> PartialEq for SliceExpr<S>

fn eq(&self, other: &SliceExpr<S>) -> 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<S: Scalar> PostprocessingStep<S> for SliceExpr<S>

fn apply( &self, owned_table: OwnedTable<S>, ) -> PostprocessingResult<OwnedTable<S>>

Apply the slice transformation to the given OwnedTable.

impl<S: Scalar> Serialize for SliceExpr<S>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
