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 fn parse(s: &str) -> Option<Self>

Read one, two or three dot separated numbers. Anything else is not a version.

Public because a version written down is not only ever a piece of a tuple. A sysroot’s manifest records the Linux release its kernel headers came out of, and the thing it has to read back is the same one, two or three numbers, so it reads them with this rather than with a second parser that would disagree about 6.12. in a year.

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.
