kuatia-types

Domain types for the kuatia ledger.

Pure data structures with no IO, no async, and minimal dependencies (serde, bitflags). This crate is the foundation — every other kuatia crate depends on it.

Key types

Type	Description
AccountId(i64)	Stable account identity
AssetId(u32)	Asset identifier — conservation boundary
EnvelopeId([u8; 32])	Content-addressed transfer hash
PostingId { transfer, index }	Posting identity within a transfer
Cent(i64)	Smallest monetary unit, checked arithmetic
Posting	Signed amount owned by one account (positive = held, negative = offset)
Transfer	Atomic unit: consumes + creates postings
Account	Versioned entity with policy, flags, and book
Book / BookId	Transfer policy scope — gates which accounts/assets may participate
PostingStatus	Active → PendingInactive → Inactive

Traits

• ToBytes — deterministic binary serialization for content-addressing
