Struct rmp_serde::decode::VariantVisitor
[−]
[src]
pub struct VariantVisitor<'a, R: Read + 'a> { // some 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>
[src]
fn new(de: &'a mut Deserializer<R>) -> VariantVisitor<'a, R>
Trait Implementations
impl<'a, R: Read> VariantVisitor for VariantVisitor<'a, R>
[src]
type Error = Error
The error type that can be returned if some error occurs during deserialization.
fn visit_variant<V>(&mut self) -> Result<V> where V: Deserialize
visit_variant
is called to identify which variant to deserialize.
fn visit_unit(&mut self) -> Result<()>
visit_unit
is called when deserializing a variant with no values.
fn visit_tuple<V>(&mut self, len: usize, visitor: V) -> Result<V::Value> where V: Visitor
visit_tuple
is called when deserializing a tuple-like variant.
fn visit_struct<V>(&mut self, fields: &'static [&'static str], visitor: V) -> Result<V::Value> where V: Visitor
visit_struct
is called when deserializing a struct-like variant.
fn visit_newtype<T>(&mut self) -> Result<T, Self::Error> where T: Deserialize
visit_newtype
is called when deserializing a variant with a single value. By default this uses the visit_tuple
method to deserialize the value. Read more
