Implementations§
source§impl Abi
impl Abi
sourcepub fn is_unsized(&self) -> bool
pub fn is_unsized(&self) -> bool
Returns true
if the layout corresponds to an unsized type.
pub fn is_sized(&self) -> bool
sourcepub fn is_uninhabited(&self) -> bool
pub fn is_uninhabited(&self) -> bool
Returns true
if this is an uninhabited type
sourcepub fn inherent_align<C: HasDataLayout>(
&self,
cx: &C,
) -> Option<AbiAndPrefAlign>
pub fn inherent_align<C: HasDataLayout>( &self, cx: &C, ) -> Option<AbiAndPrefAlign>
Returns the fixed alignment of this ABI, if any is mandated.
sourcepub fn inherent_size<C: HasDataLayout>(&self, cx: &C) -> Option<Size>
pub fn inherent_size<C: HasDataLayout>(&self, cx: &C) -> Option<Size>
Returns the fixed size of this ABI, if any is mandated.
pub fn eq_up_to_validity(&self, other: &Self) -> bool

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
