Crate table[][src]

The Table is a dynamic, compound data type that is designed to be able to represent any kind of structured data. This is especially useful in cases where the structure of data can't be precisely known at compile-time.

Tables contain Values that are indexed by Keys, both being enums that define the types that are valid for each use case. Key tends to be a limited subset of Value: some types represented by Value aren't hashable, but there aren't many Key types that wouldn't also make sense as a Value type.

Since Tables are the only compound data type provided by the crate, they serve a dual, hybrid purpose as both an unordered map and an ordered list. While the optimized list implementation and specialized accessors are not yet available, it is still possible to use Tables as lists by using numeric keys.

While the crate is named after its Table data type, Values are just as useful, if not more, since they can be tables themselves along with any of the primitive types. The Value type is also fully compatible with serde; it acts as both a (de)serializable and a (de)serializer, meaning it is an intermediate data format that can be converted to/from other data formats and to/from other (de)serializables. This makes it useful as a format for storing arbitrary data from any other format like JSON, YAML, or TOML.
