Struct rmp_serde::decode::VariantVisitor

pub struct VariantVisitor<'a, R: Read + 'a> { /* fields omitted */ }

Default variant visitor.

Note

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

Methods

impl<'a, R: Read + 'a> VariantVisitor<'a, R>

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

Trait Implementations

impl<'a, R: Read> EnumVisitor for VariantVisitor<'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 visit_variant_seed<V>(self, seed: V) -> Result<(V::Value, Self), Error> where V: DeserializeSeed

visit_variant is called to identify which variant to deserialize.

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

visit_variant is called to identify which variant to deserialize.

impl<'a, R: Read> VariantVisitor for VariantVisitor<'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 EnumVisitor.

fn visit_unit(self) -> Result<(), Error>

Called when deserializing a variant with no values.

fn visit_newtype_seed<T>(self, seed: T) -> Result<T::Value, Self::Error> where T: DeserializeSeed

Called when deserializing a variant with a single value.

fn visit_tuple<V>(self, len: usize, visitor: V) -> Result<V::Value, Error> where V: Visitor

Called when deserializing a tuple-like variant.

fn visit_struct<V>(self,
                   fields: &'static [&'static str],
                   visitor: V)
                   -> Result<V::Value, Error> where V: Visitor

Called when deserializing a struct-like variant.

fn visit_newtype<T>(self) -> Result<T, Self::Error> where T: Deserialize

Called when deserializing a variant with a single value.
