invalid version in Cargo.toml

Error message

invalid version in Cargo.toml

What it means

AppVersion::load panics because the version string baked from Cargo.toml (pkg_version) failed semver parsing. This indicates the crate's version metadata itself is malformed — a build-time invariant violation.

Solutions

1. Correct the version field in the crate's Cargo.toml to valid semver
2. Check any script that rewrites or injects the version at build time
3. Fall back to a hardcoded default with logging if parse fails
