Struct rmp_serde::decode::VariantAccess

pub struct VariantAccess<'a, R: 'a> { /* fields omitted */ }

Default variant visitor.

Note

We use default behaviour for new type, which decodes enums with a single value as a tuple.

Implementations

impl<'a, R: 'a> VariantAccess<'a, R>

pub fn new(de: &'a mut Deserializer<R>) -> Self

Trait Implementations

impl<'de, 'a, R: Read<'de>> EnumAccess<'de> for VariantAccess<'a, R>

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), 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, 'a, R: Read<'de>> VariantAccess<'de> for VariantAccess<'a, R>

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<(), Error>

Called when deserializing a variant with no values.

fn newtype_variant_seed<T>(self, seed: T) -> Result<T::Value, Self::Error> where
    T: DeserializeSeed<'de>, 

Called when deserializing a variant with a single value.

fn tuple_variant<V>(self, len: usize, visitor: V) -> Result<V::Value, 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, 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.
