Struct raptor::analysis::constants::Constants

pub struct Constants { /* fields omitted */ }

A mapping between Variables and known constants values.

Methods

impl Constants

pub fn new() -> Constants

pub fn variable(&self, variable: &Variable) -> Option<&Constant>

pub fn replace_with_constants(
    &self,
    expression: &Expression<Constant>
) -> Result<Expression<Constant>>

pub fn reduce(
    &self,
    expression: &Expression<Constant>
) -> Result<Expression<Constant>>

pub fn eval(
    &self,
    expression: &Expression<Constant>
) -> Result<Option<Constant>>

Trait Implementations

impl Clone for Constants

fn clone(&self) -> Constants

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Constants

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

Formats the value using the given formatter.

impl PartialEq<Constants> for Constants

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

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

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

This method tests for !=.

impl PartialOrd<Constants> for Constants

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

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

#[must_use] fn lt(&self, other: &Rhs) -> bool

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

#[must_use] fn le(&self, other: &Rhs) -> bool

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

#[must_use] fn gt(&self, other: &Rhs) -> bool

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

#[must_use] fn ge(&self, other: &Rhs) -> bool

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