Trait Implementations

impl<T: Clone> Clone for WithDefault<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl<T> Default for WithDefault<T>

where T: Default,

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for WithDefault<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<Option<T>> for WithDefault<T>

where WithDefault<T>: Default,

fn from(value: Option<T>) -> Self

Converts to this type from the input type.

impl<T> From<T> for WithDefault<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T> From<WithDefault<T>> for Option<T>

fn from(value: WithDefault<T>) -> Option<T>

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for WithDefault<T>

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

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

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.

impl<T> Serialize for WithDefault<T>

where T: Serialize,
