pub struct Visitor<F, S> { /* private fields */ }
Expand description
A visitor that can be used to deserialize a struct-based adjacently tagged value.
This visitor handles a struct-based adjacently tagged value, which is represented by a struct containing exactly two fields. The first field of this tuple is named according to tag-key and contains tag, the second field is named according to value-key and contains the value. Thus this visitor will return an error if the visited type is not a map or sequence with two entries.
name
is the name with which the struct that will be serialized.
The SeedFactory
provided to this visitor
provides a serde::de::DeserializeSeed
implementation depending on the tag,
which then determines how the value is going to be deserialized.
See de
for more information on
SeedFactory
and implementations thereof.
§Note
If you do not need to choose a specific deserialization-method based on the
tag, you should prefer KnownVisitor
to this visitor.
