Enum rustc_target::abi::call::HomogeneousAggregate

pub enum HomogeneousAggregate {
    Homogeneous(Reg),
    NoData,
}

Return value from the homogeneous_aggregate test function.

Variants

Homogeneous(Reg)

Yes, all the “leaf fields” of this struct are passed in the same way (specified in the Reg value).

NoData

There are no leaf fields at all.

Implementations

impl HomogeneousAggregate

pub fn unit(self) -> Option<Reg>

If this is a homogeneous aggregate, returns the homogeneous unit, else None.

fn merge( self, other: HomogeneousAggregate ) -> Result<HomogeneousAggregate, Heterogeneous>

Try to combine two HomogeneousAggregates, e.g. from two fields in the same struct. Only succeeds if only one of them has any data, or both units are identical.
