Enum rustc_target::abi::call::HomogeneousAggregate
source · pub enum HomogeneousAggregate {
Homogeneous(Reg),
NoData,
}
Expand description
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§
source§impl HomogeneousAggregate
impl HomogeneousAggregate
sourcepub fn unit(self) -> Option<Reg>
pub fn unit(self) -> Option<Reg>
If this is a homogeneous aggregate, returns the homogeneous
unit, else None
.
sourcefn merge(
self,
other: HomogeneousAggregate
) -> Result<HomogeneousAggregate, Heterogeneous>
fn merge( self, other: HomogeneousAggregate ) -> Result<HomogeneousAggregate, Heterogeneous>
Try to combine two HomogeneousAggregate
s, e.g. from two fields in
the same struct
. Only succeeds if only one of them has any data,
or both units are identical.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
