Struct boolean_expression::Cube

pub struct Cube(_);

A Cube is one (multidimensional) cube in the variable space: i.e., a particular set of variable assignments, where each variable is assigned either true, false, or "don't care".

Methods

impl Cube

pub fn true_cube(vars: usize) -> Cube

Construct an always-true cube (all variables are DontCare) for vars variables.

pub fn vars(&self) -> Iter<CubeVar>

Return an iterator over variable assignments.

pub fn merge_with(&self, other: &Cube) -> CubeMergeResult

Attempt to merge this cube with another, which may cancel one or the other (if completely covered), expand one or the other (if possible, to increase the number of DontCares and thus simplify the final expression), or merge the two into a single cube, or do nothing.

pub fn with_var(&self, idx: usize, val: CubeVar) -> Cube

Return a new cube equal to this cube, but with the particular variable

Trait Implementations

impl Clone for Cube

fn clone(&self) -> Cube

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cube

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for Cube

fn eq(&self, other: &Self) -> 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 !=.

impl Eq for Cube

impl PartialOrd for Cube

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

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.

impl Ord for Cube

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.
