//! Admin management of the alternative display currencies.
|
|
//!
|
|
//! EUR is the base/transaction currency and is shown read-only for context. The
|
|
//! admin sets each alternative currency's exchange rate (units per 1 EUR) and
|
|
//! toggles whether buyers may switch to it. The currencies themselves are fixed
|
|
//! and seeded by `initializers::currency_seeder`.
