< p > The < code > deserialize_any< / code > method. Self-describing data formats like JSON are
able to look at the serialized data and tell what it represents. For
example the JSON deserializer may see an opening curly brace (< code > {< / code > ) and
know that it is seeing a map. If the data format supports
< code > Deserializer::deserialize_any< / code > , it will drive the Visitor using whatever
type it sees in the input. JSON uses this approach when deserializing
< code > serde_json::Value< / code > which is an enum that can represent any JSON
document. Without knowing what is in a JSON document, we can deserialize
it to < code > serde_json::Value< / code > by going through
< code > Deserializer::deserialize_any< / code > .< / p >

< li >
< p > The various < code > deserialize_*< / code > methods. Non-self-describing formats like
Postcard need to be told what is in the input in order to deserialize it.
The < code > deserialize_*< / code > methods are hints to the deserializer for how to
interpret the next piece of input. Non-self-describing formats are not
able to deserialize something like < code > serde_json::Value< / code > which relies on
< code > Deserializer::deserialize_any< / code > .< / p >

< p > When implementing < code > Deserialize< / code > , you should avoid relying on
< code > Deserializer::deserialize_any< / code > unless you need to be told by the
Deserializer what type is in the input. Know that relying on
