Fields

layout_str: String

The data layout in string form, as described in the Data Layout docs linked above

endianness: Endianness

Little-endian or big-endian?

stack_alignment: Option<u32>

Natural alignment of the stack, in bits. For more, see the Data Layout docs linked above

program_address_space: AddrSpace

Address space for program memory

alloca_address_space: AddrSpace

Address space for objects created by alloca

alignments: Alignments

Alignment for various types in memory

mangling: Option<Mangling>

What mangling will be applied when the LLVM module is compiled to machine code

native_int_widths: Option<HashSet<u32>>

Native integer width(s) for the target CPU

non_integral_ptr_types: HashSet<AddrSpace>

Address spaces with non-integral pointer types

Trait Implementations

impl Clone for DataLayout

fn clone(&self) -> DataLayout

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DataLayout

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<DataLayout> for DataLayout

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.
