Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl Eq for Expression

impl<'_> From<&'_ Expression> for Enfa<u32, u32>

fn from(expression: &Expression) -> Enfa<u32, u32>

Performs the conversion.

impl<'_> From<&'_ Expression> for Nfa<Set<u32>, u32>

fn from(expression: &Expression) -> Nfa<Set<u32>, u32>

Performs the conversion.

impl<'_> From<&'_ Expression> for Dfa<Set<u32>, u32>

fn from(expression: &Expression) -> Dfa<Set<u32>, u32>

impl From<Expression> for Re

fn from(expression: Expression) -> Re

Performs the conversion.

impl From<Re> for Expression

fn from(re: Re) -> Expression

Performs the conversion.

impl Ord for Expression

fn cmp(&self, other: &Expression) -> 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<Expression> for Expression

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

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

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

This method tests for !=.

impl PartialOrd<Expression> for Expression

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

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

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

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

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

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

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

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

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

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