Struct biodivine_lib_bdd::BddValuation

pub struct BddValuation(Vec<bool>);

Exactly describes one assignment of boolean values to variables of a Bdd.

It can be used as a witness of Bdd non-emptiness, since one can evaluate every Bdd in some corresponding valuation and get a true/false result.

Implementations

impl BddValuation

pub fn new(values: Vec<bool>) -> BddValuation

Create a new valuation from a vector of variables.

pub fn all_false(num_vars: u16) -> BddValuation

Create a valuation with all variables set to false.

pub fn all_true(num_vars: u16) -> BddValuation

Create a valuation with all variables set to true.

pub fn flip_value(&mut self, variable: BddVariable)

Flip the value of a given Bdd variable.

pub fn clear(&mut self, variable: BddVariable)

pub fn set(&mut self, variable: BddVariable)

pub fn vector(self) -> Vec<bool>

Convert the valuation to its underlying vector.

pub fn value(&self, variable: BddVariable) -> bool

Get a value of a specific BDD variable in this valuation.

pub fn num_vars(&self) -> u16

Number of variables in this valuation (used mostly for consistency checks).

pub(crate) fn next(&self) -> Option<BddValuation>

(internal) "Increment" this valuation if possible. Interpret the valuation as bit-vector and perform a standard increment. This can be used to iterate over all valuations.

Trait Implementations

impl Clone for BddValuation

pub fn clone(&self) -> BddValuation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BddValuation

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

Formats the value using the given formatter.

impl Display for BddValuation

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

Formats the value using the given formatter.

impl Eq for BddValuation

impl From<BddValuation> for Bdd

Convert a BddValuation to a Bdd with, well, exactly that one valuation.

pub fn from(valuation: BddValuation) -> Self

Performs the conversion.

impl Hash for BddValuation

pub fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

pub fn index(&self, index: BddVariable) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Ord for BddValuation

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

This method tests for !=.

impl PartialOrd<BddValuation> for BddValuation

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

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

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

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

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

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

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