Trait Implementations

impl Clone for OptionalInt

fn clone(&self) -> OptionalInt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionalInt

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

Formats the value using the given formatter.

impl Default for OptionalInt

fn default() -> OptionalInt

Returns the “default value” for a type.

impl From<Option<i32>> for OptionalInt

fn from(other: Option<i32>) -> OptionalInt

Converts to this type from the input type.

impl Into<Option<i32>> for OptionalInt

fn into(self) -> Option<i32>

Converts this type into the (usually inferred) input type.

impl PartialEq for OptionalInt

fn eq(&self, other: &OptionalInt) -> 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.
