Struct WeaklyComparableProblem 

pub struct WeaklyComparableProblem<'problem>(pub &'problem Problem);

Allows for weak problem comparison.

Supports PartialEq, Eq, and PartialOrd.

Comparison is done for using the first ErrorEquality or ErrorComparison found in each problem. This is in contrast to the “strong” default comparison, which considers all causes.

Trait Implementations

impl<'problem> PartialEq for WeaklyComparableProblem<'problem>

fn eq(&self, other: &Self) -> 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<'problem> PartialOrd for WeaklyComparableProblem<'problem>

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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