Enum RuleFidelity 

pub enum RuleFidelity {
    Semantic,
    Approximate,
    Full,
}

How faithfully a rewrite preserves the input when re-rendered.

Ordered least-to-most faithful. The value is the rule’s worst-case guarantee over its declared input domain. It drives contract validation, but it does not choose the image comparison algorithm.

Variants

Semantic

Mathematical meaning is preserved, but rendering may change.

Approximate

Rendering is visually equivalent apart from minor spacing or placement.

Full

Rendering is pixel-identical before and after the rewrite.

Trait Implementations

impl Clone for RuleFidelity

fn clone(&self) -> RuleFidelity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RuleFidelity

impl Debug for RuleFidelity

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

Formats the value using the given formatter.

impl Eq for RuleFidelity

impl Hash for RuleFidelity

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 RuleFidelity

fn cmp(&self, other: &RuleFidelity) -> 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 RuleFidelity

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

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