Struct MaybeSerde 

pub struct MaybeSerde<T>(pub Option<T>);

Helper type for connect serde and maybe-serde

This type implement both serde::{Serialize, Deserialize} for all T

It’s just helper type and not necessary

you could define your own type using MaybeSer and MaybeDe

When Serialize

if T: Serialize and Option is Some then just serialize T itself (doesn’t serialize as Option!)

and T: !Serialize or Option is None then serialize None

maybe #[serde(skip_serializing_if = "T::IMPL_SERIALIZE")] attribute could be help

When Deserialize

if T: Deserialize then get Some

and T: !Deserialize just None

Tuple Fields

0: Option<T>

Trait Implementations

impl<'de, T: MaybeDe<'de>> Deserialize<'de> for MaybeSerde<T>

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> Into<Option<T>> for MaybeSerde<T>

fn into(self) -> Option<T>

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

impl<T: MaybeSer> Serialize for MaybeSerde<T>

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

where S: Serializer,

Serialize this value into the given Serde serializer.
