This enum specifies the supported conversion features which can be passed to method RegExpBuilder.with_conversion_of.

Variants

Digit

This feature converts any Unicode decimal digit to character class \d.

It takes precedence over the Word feature if both are set. Decimal digits are converted to \d, the remaining word characters to \w.

It takes precedence over the NonSpace feature if both are set. Decimal digits are converted to \d, the remaining non-whitespace characters to \S.

NonDigit

This feature converts any character which is not a Unicode decimal digit to character class \D.

It takes precedence over the NonWord feature if both are set. Non-digits which are also non-word characters are converted to \D.

It takes precedence over the NonSpace feature if both are set. Non-digits which are also non-space characters are converted to \D.

Space

This feature converts any Unicode whitespace character to character class \s.

It takes precedence over the NonDigit feature if both are set. Whitespace characters are converted to \s, the remaining non-digit characters to \D.

It takes precedence over the NonWord feature if both are set. Whitespace characters are converted to \s, the remaining non-word characters to \W.

NonSpace

This feature converts any character which is not a Unicode whitespace character to character class \S.

Word

This feature converts any Unicode word character to character class \w.

It takes precedence over the NonDigit feature if both are set. Word characters are converted to \w, the remaining non-digit characters to \D.

It takes precedence over the NonSpace feature if both are set. Word characters are converted to \w, the remaining non-space characters to \S.

NonWord

This feature converts any character which is not a Unicode word character to character class \W.

It takes precedence over the NonSpace feature if both are set. Non-words which are also non-space characters are converted to \W.

Repetition

This feature detects repeated non-overlapping substrings and converts them to {min,max} quantifier notation.

CaseInsensitivity

This feature enables case-insensitive matching of test cases so that letters match both upper and lower case.

CapturingGroup

This feature replaces non-capturing groups by capturing ones.

Trait Implementations

impl Clone for Feature

fn clone(&self) -> Feature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Feature

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

Formats the value using the given formatter.

impl Eq for Feature

impl Hash for Feature

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, 

Feeds a slice of this type into the given [Hasher].

impl Ord for Feature

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<Feature> for Feature

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Feature> for Feature

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

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

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

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

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