Struct chalk_solve::display::InvertedBoundVar

pub struct InvertedBoundVar {
    inverted_debrujin_idx: i64,
    within_idx: usize,
}

Like a BoundVar, but with the debrujin index inverted so as to create a canonical name we can use anywhere for each bound variable.

In BoundVar, the innermost bound variables have debrujin index 0, and each further out BoundVar has a debrujin index 1 higher.

In InvertedBoundVar, the outermost variables have inverted_debrujin_idx 0, and the innermost have their depth, not the other way around.

Fields

inverted_debrujin_idx: i64

The inverted debrujin index. Corresponds roughly to an inverted DebrujinIndex::depth.

within_idx: usize

The index within the debrujin index. Corresponds to BoundVar::index.

Trait Implementations

impl Clone for InvertedBoundVar

fn clone(&self) -> InvertedBoundVar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InvertedBoundVar

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

Formats the value using the given formatter.

impl Display for InvertedBoundVar

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

Formats the value using the given formatter.

impl Ord for InvertedBoundVar

fn cmp(&self, other: &InvertedBoundVar) -> 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 PartialEq for InvertedBoundVar

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for InvertedBoundVar

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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