Enum TieBreakStrategy 

pub enum TieBreakStrategy {
    LexicographicFirst,
    LexicographicLast,
    SmallestIndex,
    LargestIndex,
    SeededRandom,
}

Strategy for breaking ties when multiple solutions are equally good

Variants

LexicographicFirst

Choose first in lexicographic order of identifiers

LexicographicLast

Choose last in lexicographic order

SmallestIndex

Choose by smallest index/id

LargestIndex

Choose by largest index/id

SeededRandom

Use seeded random selection

Implementations

impl TieBreakStrategy

pub fn select<T: Ord + Clone>(&self, candidates: &[T], seed: u64) -> Option<T>

Apply tie-breaking to select from candidates

pub fn select_by<'a, T, F>( &self, candidates: &'a [T], seed: u64, compare: F, ) -> Option<&'a T>

where F: Fn(&T, &T) -> Ordering,

Apply tie-breaking with a custom comparator

pub fn sort<T: Ord>(&self, candidates: &mut [T])

Sort candidates according to this strategy

Trait Implementations

impl Clone for TieBreakStrategy

fn clone(&self) -> TieBreakStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TieBreakStrategy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TieBreakStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TieBreakStrategy

fn eq(&self, other: &TieBreakStrategy) -> 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 TieBreakStrategy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TieBreakStrategy

impl Eq for TieBreakStrategy
