Struct OSVersion

pub(in back) struct OSVersion {
    pub major: u16,
    pub minor: u8,
    pub patch: u8,
}

Deployment target or SDK version.

The size of the numbers in here are limited by Mach-O’s LC_BUILD_VERSION.

Fields

major: u16

minor: u8

patch: u8

Implementations

impl OSVersion

pub fn new(major: u16, minor: u8, patch: u8) -> OSVersion

pub fn fmt_pretty(self) -> impl Display

pub fn fmt_full(self) -> impl Display

pub fn os_minimum_deployment_target(os: &str) -> OSVersion

Minimum operating system versions currently supported by rustc.

pub fn minimum_deployment_target(target: &Target) -> OSVersion

The deployment target for the given target.

This is similar to os_minimum_deployment_target, except that on certain targets it makes sense to raise the minimum OS version.

This matches what LLVM does, see in part: https://github.com/llvm/llvm-project/blob/llvmorg-18.1.8/llvm/lib/TargetParser/Triple.cpp#L1900-L1932

Trait Implementations

impl Clone for OSVersion

fn clone(&self) -> OSVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OSVersion

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

Formats the value using the given formatter.

impl FromStr for OSVersion

fn from_str(version: &str) -> Result<OSVersion, ParseIntError>

Parse an OS version triple (SDK version or deployment target).

type Err = ParseIntError

The associated error which can be returned from parsing.

impl Hash for OSVersion

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 Ord for OSVersion

fn cmp(&self, other: &OSVersion) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for OSVersion

fn eq(&self, other: &OSVersion) -> 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 PartialOrd for OSVersion

fn partial_cmp(&self, other: &OSVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for OSVersion

impl Eq for OSVersion

impl StructuralPartialEq for OSVersion

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.
