Enum Difficulty 

pub enum Difficulty {
    Trivial,
    Easy,
    Medium,
    Hard,
    VeryHard,
}

Difficulty estimate for proof steps.

Variants

Trivial

Trivial step (e.g., axiom, reflexivity)

Easy

Easy step (e.g., simple resolution)

Medium

Medium difficulty

Hard

Hard step (e.g., complex theory reasoning)

VeryHard

Very hard step (e.g., quantifier instantiation)

Trait Implementations

impl Clone for Difficulty

fn clone(&self) -> Difficulty

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Difficulty

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

Formats the value using the given formatter.

impl Default for Difficulty

fn default() -> Difficulty

Returns the “default value” for a type.

impl Display for Difficulty

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

Formats the value using the given formatter.

impl Hash for Difficulty

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Difficulty

fn cmp(&self, other: &Difficulty) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Difficulty

fn eq(&self, other: &Difficulty) -> 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 PartialOrd for Difficulty

fn partial_cmp(&self, other: &Difficulty) -> 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.
