Struct mz_expr::row::collection::RunIter

struct RunIter<'a, F> {
    collection: &'a RowCollection,
    cmp: &'a F,
    range: Range<usize>,
}

Iterator-like struct to help with extracting rows in sorted order from RowCollection.

Fields

collection: &'a RowCollection

cmp: &'a F

range: Range<usize>

Trait Implementations

impl<'a, F> Ord for RunIter<'a, F>

where F: Fn(&RowRef, &RowRef) -> Ordering,

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a, F> PartialEq for RunIter<'a, F>

where F: Fn(&RowRef, &RowRef) -> Ordering,

fn eq(&self, other: &Self) -> 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<'a, F> PartialOrd for RunIter<'a, F>

where F: Fn(&RowRef, &RowRef) -> Ordering,

fn partial_cmp(&self, other: &Self) -> 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.

impl<'a, F> Eq for RunIter<'a, F>

where F: Fn(&RowRef, &RowRef) -> Ordering,
