pub struct OptionSeed<S>(pub S);

DeserializeSeed instances for optional values

Trait Implementations

impl<'de, S> DeserializeSeed<'de> for OptionSeed<S> where
    S: DeserializeSeed<'de>, 

type Value = Option<S::Value>

The type produced by using this seed.

fn deserialize<D>(self, deserializer: D) -> Result<Self::Value, D::Error> where
    D: Deserializer<'de>, 

Equivalent to the more common Deserialize::deserialize method, except with some initial piece of data (the seed) passed in.
