About

Simple binary serialization (SBS) features:

• schema based

• small schema language optimized for human readability

• schema re-usability and organization into modules

• small number of built in types

• polymorphic data types

• binary serialization

• designed to enable simple and efficient implementation

• optimized for small encoded data size

Example of SBS schema:

module Module

Entry(K, V) = Tuple {
    key: K
    value: V
}

Collection(K) = Union {
    null: None
    bool: Entry(K, Boolean)
    int: Entry(K, Integer)
    float: Entry(K, Float)
    str: Entry(K, String)
    bytes: Entry(K, Bytes)
}

IntKeyCollection = Collection(Integer)

StrKeyCollection = Collection(String)
