| {{! Note the use of the nested "eq" helper below: "#if" expects a single |
| parameter which is evaluated for "truthiness". The "eq" helper takes two |
| parameters and compares them against each other using "param1 == param2", |
| returning "true" if they match and nothing otherwise. }} |
| {{! Also note the use of the "ua" helper: the device.memory.units variable |
| normally serializes as the full word, e.g. "megabytes", but the Qemu flag |
| it populates expects a single-character abbreviation, e.g. "M". The "ua" |
| helper calls a rust function to perform that substitution. If the parameter |
| doesn't deserialize to a DataUnits, the helper just returns the usual |
| serialized value of the parameter. }} |
