pub struct PgMoney(pub i64);
postgres_backend
only.Expand description
Money is represented in Postgres as a 64 bit signed integer. This struct is a dumb wrapper
type, meant only to indicate the integer’s meaning. The fractional precision of the value is
determined by the lc_monetary
setting of the database.
This struct is re-exported as Cents
as a convenient and conventional expression of a typical
unit of 1/100th of currency. For other names or precisions, users might consider a differently
named use
of the PgMoney
struct.
use diesel::data_types::PgMoney as Pence; // 1/100th unit of Pound
use diesel::data_types::PgMoney as Fils; // 1/1000th unit of Dinar
