Enum Target 

pub enum Target {
    X86_64Linux,
    Aarch64Linux,
    Aarch64Macos,
}

A compilation target consisting of an architecture and operating system.

Variants

X86_64Linux

x86-64 Linux (System V AMD64 ABI)

Aarch64Linux

AArch64 Linux (AAPCS64 ABI)

Aarch64Macos

AArch64 macOS (Apple Silicon, AAPCS64 with Apple extensions)

Implementations

impl Target

pub fn host() -> Target

Detect the host target at compile time.

Returns the target that matches the current compilation environment. This is useful for defaulting to native compilation.

pub fn arch(&self) -> Arch

Returns the architecture component of this target.

pub fn os(&self) -> Os

Returns the operating system component of this target.

pub fn elf_machine(&self) -> Option<u16>

Returns the ELF e_machine value for this target, if it uses ELF format.

This is used when generating ELF object files and executables. Returns None for targets that don’t use ELF (e.g., macOS uses Mach-O).

pub fn page_size(&self) -> u64

Returns the default page size for this target in bytes.

This is used for executable segment alignment.

pub fn default_base_addr(&self) -> u64

Returns the default base address for executables on this target.

This is the virtual address where the executable is loaded.

pub fn pointer_size(&self) -> u32

Returns the pointer size in bytes for this target.

pub fn stack_alignment(&self) -> u32

Returns the required stack alignment in bytes for this target.

This is the alignment required at function call boundaries.

pub fn triple(&self) -> &'static str

Returns the triple string for this target (e.g., “x86_64-unknown-linux-gnu”).

This can be useful for invoking external tools like system linkers.

pub fn is_macho(&self) -> bool

Returns whether this target uses Mach-O object format (macOS).

pub fn is_elf(&self) -> bool

Returns whether this target uses ELF object format (Linux).

pub fn macos_min_version(&self) -> Option<u32>

Returns the minimum macOS version for this target, encoded for Mach-O.

The version is encoded as 0x00XXYYPP where XX is major, YY is minor, PP is patch. For example, macOS 11.0.0 (Big Sur) is encoded as 0x000B0000.

Returns None for non-macOS targets.

Note: macOS 11.0 (Big Sur) was the first version to support Apple Silicon (ARM64), which is why it’s the minimum for Aarch64Macos.

pub fn all() -> &'static [Target]

Returns all supported targets.

pub fn all_names() -> &'static str

Returns a comma-separated string of all target names for help text.

Trait Implementations

impl Clone for Target

fn clone(&self) -> Target

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Target

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

Formats the value using the given formatter.

impl Default for Target

fn default() -> Target

Returns the host target as the default.

This allows code to write Target::default() instead of Target::host(), which is useful for struct initialization with ..Default::default().

impl Display for Target

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

Formats the value using the given formatter.

impl FromStr for Target

type Err = ParseTargetError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Target, <Target as FromStr>::Err>

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

impl Hash for Target

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Target

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Target

impl Eq for Target

impl StructuralPartialEq for Target
