Function escape_version 

pub fn escape_version(version: &str) -> String

Escapes a Go version string for safe interpolation into proxy.golang.org @v/{version}.info and @v/{version}.mod URLs.

Mirrors escape_module_path’s case-encoding convention: uppercase letters become ! + lowercase (the Go module-proxy case-folding rule), since a raw uppercase version segment — legal in a semver prerelease identifier such as v1.7.0-RC — otherwise 404s against the proxy. Every other character outside [a-z0-9.+-] is percent-encoded, preventing ?, #, or whitespace from being interpreted as URL syntax (starting a query string or fragment) instead of literal version content.

Examples

use deps_go::escape_version;

assert_eq!(escape_version("v1.9.1"), "v1.9.1");
assert_eq!(escape_version("v2.0.0+incompatible"), "v2.0.0+incompatible");
assert_eq!(escape_version("v1.7.0-RC"), "v1.7.0-!r!c");
assert_eq!(escape_version("v1?a=b"), "v1%3Fa%3Db");
