go-api-declarations liquid Unit MultiplyBy method sapcc💡 Result:
In
github.com/sapcc/go-api-declarations/liquid, there is noUnit.MultiplyBymethod. Instead, unit conversion is modeled via:func (u Unit) Base() (Unit, uint64)which returns the base unit plus a multiplier to convert values inuinto that base unit. For all binary-size units (KiB,MiB, …), the base unit isB(bytes); otherwise it returns(u, 1). [1][2]Multiplier mapping (from
Base()):KiB=1<<10,MiB=1<<20,GiB=1<<30,TiB=1<<40,PiB=1<<50,EiB=1<<60. [2]How to “multiply by” in practice:
