Struct Version 

pub struct Version { /* private fields */ }

A version attached to an OS or to an environment.

Minor and patch are optional and absent is not zero. macos.13 and macos.13.0 are the same deployment target, and a version type that normalized one to the other would not round trip, so both spellings survive formatting and compare equal.

Implementations

impl Version

pub const fn major(major: u32) -> Self

A version with only a major component. linux-gnu.2 is not useful and wasip1 is exactly this.

pub const fn new(major: u32, minor: u32) -> Self

A two component version, which is what a glibc version is.

pub const fn full(major: u32, minor: u32, patch: u32) -> Self

A three component version, which is what an SDK version is.

pub const fn major_part(self) -> u32

The major component.

pub const fn minor_part(self) -> Option<u32>

The minor component, if the tuple gave one.

pub const fn patch_part(self) -> Option<u32>

The patch component, if the tuple gave one.

pub const fn to_triple(self) -> (u32, u32, u32)

The version as a three component tuple with absent components read as zero, which is the form to compare in. Do not use it to format: formatting from this loses the distinction between 13 and 13.0.

pub const fn at_least(self, other: Version) -> bool

Whether this version is at least other, comparing on the zero filled form.

pub fn to_llvm_string(self) -> String

The LLVM spelling, which always has three components. macosx13.0.0 rather than macos.13.
