Converts to this type from the input type.

impl<A, B> From<Optionals2<A, B>> for (Option<A>, Option<B>)

fn from(value: Optionals2<A, B>) -> Self

Converts to this type from the input type.

impl<A: Hash, B: Hash> Hash for Optionals2<A, B>

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,

impl<A: Ord, B: Ord> Ord for Optionals2<A, B>

fn cmp(&self, other: &Optionals2<A, B>) -> 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<'a, A, B> Parse<'a> for Optionals2<A, B>

where A: Parse<'a> + Peek<'a>, B: Parse<'a> + Peek<'a>,

fn parse<I>(p: &mut Parser<'a, I>) -> ParserResult<Self>

where I: Iterator<Item = Cursor> + Clone,

fn try_parse<I>(p: &mut Parser<'a, I>) -> Result<Self>

impl<A: PartialEq, B: PartialEq> PartialEq for Optionals2<A, B>

fn eq(&self, other: &Optionals2<A, B>) -> 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.

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.
