Struct genco::java::Optional

pub struct Optional<'el> {
    pub value: Box<Java<'el>>,
    pub field: Box<Java<'el>>,
}

An optional type.

Fields

value: Box<Java<'el>>

The type that is optional.

field: Box<Java<'el>>

The complete optional field type, including wrapper.

Trait Implementations

impl<'el> Clone for Optional<'el>

fn clone(&self) -> Optional<'el>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'el> Debug for Optional<'el>

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

Formats the value using the given formatter.

impl<'el> Eq for Optional<'el>

impl<'el> Hash for Optional<'el>

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<'el> Ord for Optional<'el>

fn cmp(&self, other: &Optional<'el>) -> 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<'el> PartialEq<Optional<'el>> for Optional<'el>

fn eq(&self, other: &Optional<'el>) -> bool

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

fn ne(&self, other: &Optional<'el>) -> bool

This method tests for !=.

impl<'el> PartialOrd<Optional<'el>> for Optional<'el>

fn partial_cmp(&self, other: &Optional<'el>) -> Option<Ordering>

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

fn lt(&self, other: &Optional<'el>) -> bool

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

fn le(&self, other: &Optional<'el>) -> bool

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

fn gt(&self, other: &Optional<'el>) -> bool

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

fn ge(&self, other: &Optional<'el>) -> bool

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