Struct mmrbi::Version

pub struct Version {
    pub tool_name: String,
    pub version: Version,
    pub hash: String,
    pub date: String,
}

This is supported on crate feature version only.

Parsed "rustup 1.22.1 (b01adbbc3 2020-07-08)", decomposed into:
{ tool_name: "rustup", version: "1.22.1", hash: "b01adbbc3", date: "2020-07-08" }

Fields

tool_name: String

The tool name (e.g. "rustup")

version: Version

The semver (e.g. "1.22.1")

hash: String

The hash (typically a git commit, e.g. "b01adbbc3")

date: String

The date (typically in yyyy-mm-dd format, e.g. "2020-07-08")

Implementations

impl Version

pub fn parse_rusty_version(line: &str) -> Result<Self>

Parse input in the format "{tool_name} {version}" or "{tool_name} {version} ({hash} {date})"
