Trait maybe_serde::MaybeDe

pub trait MaybeDe<'de>: Sized {
    const IMPL_DESERIALIZE: bool;

    fn maybe_deserialize<D>(deserializer: D) -> Option<Result<Self, D::Error>>
    where
        D: Deserializer<'de>;

Maybe implement Deserialize

This trait is impl for all types

If type implement Deserialize then maybe_deserialize return Deserialize::deserialize value with Some

Otherwise if type doesn't implement Deserialize then maybe_deserialize return just None
