Struct PaymentAmount 

pub struct PaymentAmount { /* private fields */ }

Amount of value in a payment flow, expressed as decimal text plus asset.

Validation

PaymentAmount::new accepts a value consisting only of ASCII digits and at most one decimal point, with at least one digit. Leading + and - signs are rejected. Values such as .5 and 10. are accepted. The asset must be non-empty and contain no control characters. Beyond these checks, Paykit defines no range, precision, scale, normalization, or asset-registry policy.

Fields are private so validation survives construction and cloning.

let mut amount = paykit_lib::PaymentAmount::new("1", "btc").unwrap();
amount.value = "invalid".into();
