Crate semver_macro

A proc-macro for semver::Version

This crate contains macros to parse semver::Versions at compile-time. Currently only versions without pre-release and build metadata identifier are supported.

Example

use semver::Version;
use semver_macro::{version, env_version};

// parse from string literal
const FROM_LITERAL: Version = version!("0.1.0");

// parse from environment variable
const FROM_ENV: Version = env_version!("CARGO_PKG_VERSION");

Macros

env_version

Macro that parses a semver::Version from an environment variable and outputs it as a constant expression.
