Struct diesel::pg::data_types::Cents

[+] Show declaration

pub struct Cents(pub i64);

[−] 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
