Struct Pillar 

pub struct Pillar {
    pub entities: Vec<EntityReference>,
}

A pillar is a group of entity references that share the same variable value.

All entities in a pillar have the same value for a specific planning variable, which allows them to be moved together atomically.

Fields

entities: Vec<EntityReference>

The entity references in this pillar.

Implementations

impl Pillar

pub fn new(entities: Vec<EntityReference>) -> Self

Creates a new pillar with the given entities.

pub fn size(&self) -> usize

Returns the number of entities in this pillar.

pub fn is_empty(&self) -> bool

Returns true if this pillar is empty.

pub fn first(&self) -> Option<&EntityReference>

Returns the first entity reference in this pillar.

pub fn iter(&self) -> impl Iterator<Item = &EntityReference>

Returns an iterator over the entity references.

Trait Implementations

impl Clone for Pillar

fn clone(&self) -> Pillar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pillar

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

Formats the value using the given formatter.

impl PartialEq for Pillar

fn eq(&self, other: &Pillar) -> 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.
