Enum Quality 

pub enum Quality {
    Complete,
    Partial,
    Ambiguous,
}

How complete a determinate answer is.

The qualities of an answer that exists. “No answer” is not one of them: it is Outcome::Indeterminate.

Variants

Complete

Every intended atom was available and unambiguous.

Partial

Computed, but some intended atoms were not available.

Ambiguous

Several defensible answers exist; one was chosen deterministically.

Implementations

impl Quality

pub fn worst(self, other: Quality) -> Quality

The weaker of two qualities, as a combined result is only as good as its parts.

Trait Implementations

impl Clone for Quality

fn clone(&self) -> Quality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Quality

impl Debug for Quality

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

Formats the value using the given formatter.

impl Default for Quality

fn default() -> Quality

Returns the “default value” for a type.

impl Eq for Quality

impl From<Quality> for Status

fn from(quality: Quality) -> Status

Converts to this type from the input type.

impl Hash for Quality

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

where __H: Hasher,

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 Quality

fn cmp(&self, other: &Quality) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Quality

fn eq(&self, other: &Quality) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Quality

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