kuatia-money

Monetary amounts for the kuatia ledger.

Cent is a signed amount in an asset's smallest unit. It wraps an integer whose width is an internal detail: the public API never names the backing type, and no serialized form reveals it. The width is chosen once at compile time through the Backing alias, which defaults to i64 and switches to i128 under the i128 cargo feature.

All arithmetic is checked. Addition, subtraction, and negation return OverflowError instead of wrapping, so the ledger's per-asset conservation sum can never silently round or overflow.

Key types

Type Description
Cent Signed amount in an asset's smallest unit, checked arithmetic
Backing The integer type behind every Cent (i64, or i128 via feature)
CentBacking Trait an integer must satisfy to back a Cent
OverflowError Returned when a checked operation would overflow

Features

  • i128 — swap the backing integer from i64 to i128 across the whole dependency chain.
