Trait Implementations

impl<T> Clone for OptionSerializer<T>

where T: Clone,

fn clone(&self) -> OptionSerializer<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for OptionSerializer<T>

where T: Debug,

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

Formats the value using the given formatter.

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

where T: Deserialize<'de>,

fn deserialize<D>( deserializer: D, ) -> Result<OptionSerializer<T>, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<Option<T>> for OptionSerializer<T>

fn from(option: Option<T>) -> OptionSerializer<T>

Converts to this type from the input type.

impl<T> PartialEq for OptionSerializer<T>

where T: PartialEq,

fn eq(&self, other: &OptionSerializer<T>) -> 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.

impl<T> Serialize for OptionSerializer<T>

where T: Serialize,

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
