Trait Implementations

impl<T: Debug> Debug for SingleMapDeserializer<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, T> EnumAccess<'de> for SingleMapDeserializer<T> where
    T: IntoDeserializer<'de, Error>, 

type Error = Error

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

type Variant = Self

The Visitor that will be used to deserialize the content of the enum variant.

fn variant_seed<V>(
    self,
    seed: V
) -> Result<(V::Value, Self::Variant), Self::Error> where
    V: DeserializeSeed<'de>, 

variant is called to identify which variant to deserialize.

fn variant<V>(self) -> Result<(V, Self::Variant), Self::Error> where
    V: Deserialize<'de>, 

variant is called to identify which variant to deserialize.

impl<'de, T> MapAccess<'de> for SingleMapDeserializer<T> where
    T: IntoDeserializer<'de, Error>, 

type Error = Error

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

fn next_key_seed<K>(&mut self, seed: K) -> Result<Option<K::Value>, Self::Error> where
    K: DeserializeSeed<'de>, 

This returns Ok(Some(key)) for the next key in the map, or Ok(None) if there are no more remaining entries.

fn next_value_seed<V>(&mut self, seed: V) -> Result<V::Value, Self::Error> where
    V: DeserializeSeed<'de>, 

This returns a Ok(value) for the next value in the map.

fn next_entry_seed<K, V>(
    &mut self,
    kseed: K,
    vseed: V
) -> Result<Option<(<K as DeserializeSeed<'de>>::Value, <V as DeserializeSeed<'de>>::Value)>, Self::Error> where
    V: DeserializeSeed<'de>,
    K: DeserializeSeed<'de>, 

This returns Ok(Some((key, value))) for the next (key-value) pair in the map, or Ok(None) if there are no more remaining items.

fn next_key<K>(&mut self) -> Result<Option<K>, Self::Error> where
    K: Deserialize<'de>, 

This returns Ok(Some(key)) for the next key in the map, or Ok(None) if there are no more remaining entries.

fn next_value<V>(&mut self) -> Result<V, Self::Error> where
    V: Deserialize<'de>, 

This returns a Ok(value) for the next value in the map.

fn next_entry<K, V>(&mut self) -> Result<Option<(K, V)>, Self::Error> where
    V: Deserialize<'de>,
    K: Deserialize<'de>, 

This returns Ok(Some((key, value))) for the next (key-value) pair in the map, or Ok(None) if there are no more remaining items.

fn size_hint(&self) -> Option<usize>

Returns the number of entries remaining in the map, if known.

impl<'de, T> VariantAccess<'de> for SingleMapDeserializer<T> where
    T: IntoDeserializer<'de, Error>, 

type Error = Error

The error type that can be returned if some error occurs during deserialization. Must match the error type of our EnumAccess.

fn unit_variant(self) -> Result<(), Self::Error>

Called when deserializing a variant with no values.

fn newtype_variant_seed<D>(self, seed: D) -> Result<D::Value, Self::Error> where
    D: DeserializeSeed<'de>, 

Called when deserializing a variant with a single value.

fn tuple_variant<V>(
    self,
    _len: usize,
    _visitor: V
) -> Result<V::Value, Self::Error> where
    V: Visitor<'de>, 

Called when deserializing a tuple-like variant.

fn struct_variant<V>(
    self,
    _fields: &'static [&'static str],
    _visitor: V
) -> Result<V::Value, Self::Error> where
    V: Visitor<'de>, 

Called when deserializing a struct-like variant.

fn newtype_variant<T>(self) -> Result<T, Self::Error> where
    T: Deserialize<'de>, 

Called when deserializing a variant with a single value.
