Struct ReferenceBuses 

pub struct ReferenceBuses(/* private fields */);

The reference (slack) buses of a problem instance, as dense bus indices in ascending order.

Every island of a network needs a reference bus, and the instance builders check that before they assemble, so a network of several islands gives several entries. A formulation grounds every entry. One that can ground only one bus calls single, which states the condition it needs instead of taking the first entry and grounding one island of many.

Implementations

impl ReferenceBuses

pub fn new(buses: Vec<usize>) -> Self

pub fn iter(&self) -> Iter<'_, usize>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn single(&self) -> Result<usize>

The one reference bus.

Errors

powerio::Error::ReferenceBusCount unless the set holds exactly one bus.

Trait Implementations

impl AsRef<[usize]> for ReferenceBuses

fn as_ref(&self) -> &[usize]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ReferenceBuses

fn clone(&self) -> ReferenceBuses

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReferenceBuses

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReferenceBuses

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> IntoIterator for &'a ReferenceBuses

type Item = &'a usize

The type of the elements being iterated over.

type IntoIter = Iter<'a, usize>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for ReferenceBuses

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

impl Serialize for ReferenceBuses

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
