Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

endianness: Endian

The endianness of the target.

natural_stack_alignment: Option<Align>

The target’s natural stack alignment, if present.

program_address_space: AddressSpace

The address space for program memory.

global_variable_address_space: AddressSpace

The address space for global variables.

alloca_address_space: AddressSpace

The address space for objects created by alloca.

type_alignments: TypeAlignSpecs

Non-pointer type alignment specifications for the target.

pointer_alignments: PointerAlignSpecs

Pointer alignment specifications for the target.

aggregate_alignment: Align

Aggregate alignment for the target.

function_pointer_alignment: Option<FunctionPointerAlign>

Function pointer alignment for the target, if present.

mangling: Option<Mangling>

The target’s symbol mangling discipline, if present.

native_integer_widths: Vec<u32>

A list of integer widths (in bits) that are efficiently supported by the target.

non_integral_address_spaces: Vec<AddressSpace>

A list of address spaces that use non-integral pointers.

Trait Implementations

impl Default for DataLayout

fn default() -> Self

Returns the “default value” for a type.

impl FromStr for DataLayout

type Err = DataLayoutError

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.
