KVDS is a format for encoding key-value lists where the
key is a single u8 and the value is an array (called a
Vec in Rust) of u8. There can be multiple values
for one key, i.e. there can be more than one of the same
key. Furthermore, the key-value pairs are kept in
order. KVDS is meant for encoding documents, much like
XML.
This crate, KVDS, is meant to be used as a Rust library. See the example for more information.
One of the most common types of data held in the value field is a string. In Rust, a Vec<u8> can be converted to a String as follows:
rust
String::from(std::str::from_utf8(&VEC_U8[..]).unwrap());
The String can be converted back as follows:
rust
STRING.as_bytes().to_vec();
Keys can only be one byte. There are therefore 256 distinct keys.
Values can be up to 18.4 exabytes. Needless to say, there are many, many unique combinations.
(AFAIK, 18.4 exabytes is also the theoretical limit for RAM in 64-bit CPUs).
