b3-rs

A Rust implementation of B3 (Better Binary Buffers).

This library is in very early stages of development! There is no guarantee of API stability until we reach v1.0.0.

Parts of this library are heavily based on the original Python B3 implementation.

Usage

```rust use b3_rs::{Item, ItemKey, ItemValue};

// Creating an item for a simple type let stringitem = Item::from("item value").withkey(ItemKey::from("item key")); let integeritem = Item::from(123456u64).withkey(ItemKey::from(0u64));

// Creating an item collection let dictitem = Item::new( ItemKey::NoKey, ItemValue::CompositeDict( vec![stringitem, integer_item] ), );

// Encoding items into the wire format let encoded = dict_item.encode()?;

// Decoding items from the wire format let (decoded, bytecount) = Item::decode(&encoded)?; asserteq!(bytecount, encoded.len()); asserteq!(dict_item, decoded); ```

Caveats

Unimplemented item types

The following item types are currently unimplemented:

• Decimal (type 10)
• Sched (type 13)
• Complex (type 16)

The error b3_rs::Error::UnimplementedB3TypeError will be returned when a message contains any of these types.
