Enum ToolVersionStatus 

pub enum ToolVersionStatus {
    Supported {
        version: String,
    },
    Unsupported {
        first_line: Option<String>,
        exit_status: Option<i32>,
    },
    CommandFailed {
        first_line: Option<String>,
        exit_status: Option<i32>,
    },
    NotRun {
        reason: String,
    },
}

The outcome of asking a resolved tool for its --version (T17.3 — was a bare Option<String> that silently turned an old fork’s “unknown option” or a non-zero exit into a “version” string). The tool ran (or didn’t) is now distinguished from the tool has a usable version: a --version that the tool rejected (old forks like OpenBSD/DragonFly zic) is Unsupported, never a fake version.

Variants

Supported

--version exited 0 and printed a usable first line.

Fields

version: String

Unsupported

--version exited non-zero — the tool does not support the flag (typical of old zic forks, which print usage to stderr and exit 1). The captured first line + exit status are recorded, but it is not treated as a version.

Fields

first_line: Option<String>

exit_status: Option<i32>

CommandFailed

--version ran but neither cleanly succeeded with a version nor cleanly rejected the flag (e.g. exited 0 with no usable output, or was terminated by a signal — exit_status: None).

Fields

first_line: Option<String>

exit_status: Option<i32>

NotRun

The --version command could not be spawned at all (resolved file not executable, race, …).

Fields

reason: String

Trait Implementations

impl Clone for ToolVersionStatus

fn clone(&self) -> ToolVersionStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolVersionStatus

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

impl Eq for ToolVersionStatus

impl PartialEq for ToolVersionStatus

fn eq(&self, other: &ToolVersionStatus) -> 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.
