[−][src]Struct maybe_serde::MaybeSerde
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
