and what you are doing are two completely different paths into the library. This by-key access is an implementation of Index<_>
and will panic if the key does not exist.
This is what you are seeing in your code.
The real way to do what you are trying to do is indeed by using get()
, which will return an Option
, but first, we're going to sort out the case where the toml
you feed isn't a table, like so:
QUESTION
I am using toml-rs and serde_derive to deserialize TOML files my app uses to describe data structures.
I have everything working with my first data structure which corresponds to one TOML file definition with obligatory and optional fields.
Now I want to use it to deserialize another data structure that is described in another TOML file, with different fields.
How do I specify to the deserializer (I am using toml::from_str(&contents)
) which structure type I want to deserialize into?
Related question - is it possible to put the type into the file itself, so that deserialization can be more generic, and the deserializer can detect the type to deserialize from the file itself?

deserializes into the type that is expected from the expression. So
