Struct MajorMinor

source
#[repr(C)]
pub struct MajorMinor { pub major: u16, pub minor: u16, }
Expand description

A type representing a major, minor version pair.

This is not part of the spec, but versions in the spec are frequently represented as a major_version, minor_version pair. This type encodes those as a single type, which is useful for some of the generated code that parses out a version.

Fields§

§major: u16

The major version number

§minor: u16

The minor version number
