Work in progress

Serde support for Extensible Data Notation (edn), the S-expressions superset used as syntax for the clojure programming language.
At the moment it uses edn.rs to bootstrap development. The parser will be replaced in the future.

serde_edn also provides its own Value type and edn! macro for constructing values

serde_edn is heavily inspired by and modeled after serde_json

Working assumptions

Serialization:

from Rust	to edn
tuple, tuple struct	list (or vector ?)
struct, struct variant	map keyed with keywords
enum	map?
unit variant	keyword
Vec	vector
HashMap, BTreeMap	map
HashSet, BTreeSet	set
LinkedList	list

Unresolved questions

• how to map all edn constructs to rust types
• handling of symbols and keywords
• restrict deserialization to matching types ? (i.e. do we want to allow deserializing a Vec from an edn #{...} set ?)

Working items list

• Serialization to string
• Serialization to Value
• Deserialization from str (partial support)
• Deserialization from Value (partial support)
• edn! macro
• utility functions for Value

Limitations

• the edn! macro has some inherent limitations, due to the different treatment of whitespace and tokens between rust and edn syntax.

Future goals

• fix or replace edn.rs to conform to spec
• bignum support
