Expand description

Deserializes some variant of an optional value.

Implementations§

Source§

impl<D> SomeAccess<D>

Source

pub fn new(de: D) -> SomeAccess<D>

Returns a new SomeAccess with a given deserializer for the some variant.

Trait Implementations§

Source§

impl<'de, D> SumAccess<'de> for SomeAccess<D>
where D: Deserializer<'de>,

Source§

type Error = <D as Deserializer<'de>>::Error

The error type that can be returned if some error occurs during deserialization.
Source§

type Variant = SomeAccess<D>

The visitor used to deserialize the content of the sum variant.
Source§

fn variant<V>( self, visitor: V, ) -> Result<(<V as VariantVisitor<'de>>::Output, <SomeAccess<D> as SumAccess<'de>>::Variant), <SomeAccess<D> as SumAccess<'de>>::Error>
where V: VariantVisitor<'de>,
