Struct VersionInfo 

pub struct VersionInfo { /* private fields */ }

Parsed output from the version command’s multi-line response.

The response from OpenVPN looks like:

OpenVPN Version: OpenVPN 2.6.9 x86_64-pc-linux-gnu [SSL (OpenSSL)] ...
Management Interface Version: 5
END

Note: OpenVPN ≥ 2.6.16 shortened the header to Management Version: 5 (without “Interface”). Both forms are accepted.

This struct extracts the management interface version (which is the field most consumers need for feature-gating) and keeps the raw lines for anything else.

Examples

use openvpn_mgmt_codec::VersionInfo;

let lines = vec![
    "OpenVPN Version: OpenVPN 2.6.9 x86_64-pc-linux-gnu [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [MH/PKTINFO] [AEAD]".to_string(),
    "Management Interface Version: 5".to_string(),
];
let info = VersionInfo::parse(&lines);
assert_eq!(info.management_version(), Some(5));
assert!(info.openvpn_version_line().unwrap().contains("2.6.9"));

Implementations

impl VersionInfo

pub fn parse(lines: &[String]) -> Self

Parse a version command’s multi-line response into structured data.

Lines that don’t match known prefixes are preserved in raw_lines for forward compatibility.

pub fn management_version(&self) -> Option<u32>

The management interface protocol version (e.g. 5).

Returns None if the line was missing or unparseable. Use this to gate features: for instance, client-pending-auth requires management version >= 5 (OpenVPN 2.5+).

pub fn openvpn_version_line(&self) -> Option<&str>

The full OpenVPN Version: line (e.g. "OpenVPN Version: OpenVPN 2.6.9 ...").

pub fn raw_lines(&self) -> &[String]

All raw lines from the response, for anything not explicitly parsed.

Trait Implementations

impl Clone for VersionInfo

fn clone(&self) -> VersionInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VersionInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for VersionInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for VersionInfo

fn eq(&self, other: &VersionInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
