Enum ReferenceExpression 

pub enum ReferenceExpression<T: Clone> {
    Constant(T),
    Variable(usize),
    Table(TableExpression<T>),
}

Expression referring to a constant or a variable.

Variants

Constant(T)

Constant.

Variable(usize)

Variable index.

Table(TableExpression<T>)

Constant in a table.

Implementations

impl<T: Clone> ReferenceExpression<T>

pub fn simplify( &self, registry: &TableRegistry, tables: &TableData<T>, ) -> ReferenceExpression<T>

Returns a simplified version by precomputation.

Panics

Panics if a min/max reduce operation is performed on an empty set or vector.

impl ReferenceExpression<Set>

pub fn eval<'a, S: StateInterface>( &'a self, state: &'a S, function_cache: &mut StateFunctionCache, state_functions: &StateFunctions, registry: &'a TableRegistry, ) -> &'a Set

Returns the evaluation result.

Panics

Panics if the cost of the transition state is used or a min/max reduce operation is performed on an empty set or vector.

impl ReferenceExpression<Vector>

pub fn eval<'a, U: StateInterface>( &'a self, state: &'a U, function_cache: &mut StateFunctionCache, state_functions: &StateFunctions, registry: &'a TableRegistry, ) -> &'a Vector

Returns the evaluation result.

Panics

Panics if the cost of the transition state is used or a min/max reduce operation is performed on an empty set or vector.

Trait Implementations

impl<T: Clone + Clone> Clone for ReferenceExpression<T>

fn clone(&self) -> ReferenceExpression<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Clone> Debug for ReferenceExpression<T>

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

Formats the value using the given formatter.

impl<T: PartialEq + Clone> PartialEq for ReferenceExpression<T>

fn eq(&self, other: &ReferenceExpression<T>) -> bool

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

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

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