Struct PartIndices

struct PartIndices {
    sorted_indices: VecDeque<usize>,
    next_index: usize,
}

Indices into a part. For most parts, all we need is a single index to the current entry… but for parts that have never been consolidated, this would return entries in the “wrong” order, and it’s expensive to re-sort the columnar data. Instead, we sort a list of indices and then use this helper to hand them out in the correct order.

Fields

sorted_indices: VecDeque<usize>

next_index: usize

Implementations

impl PartIndices

fn index(&self) -> usize

fn inc(&mut self)

Trait Implementations

impl Debug for PartIndices

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

Formats the value using the given formatter.

impl Default for PartIndices

fn default() -> PartIndices

Returns the “default value” for a type.

impl Ord for PartIndices

fn cmp(&self, other: &PartIndices) -> 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,

Restrict a value to a certain interval.

impl PartialEq for PartIndices

fn eq(&self, other: &PartIndices) -> bool

Tests for self and other values to be equal, and is used by ==.

const 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 PartIndices

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