Enum ParseNumJobsError 

pub enum ParseNumJobsError {
    Zero {
        input: String,
    },
    NotAPositiveInteger {
        input: String,
    },
}

Error returned by NumJobs::from_str when the input is neither auto nor a usable positive integer.

Named (rather than a bare String) so callers can match the failure mode and recover the rejected input via ParseNumJobsError::input, matching the typed-error convention of ParseMetricError / ParseLangError.

Deliberately exhaustive: usize::from_str collapses every malformed integer (negative, overflowing, non-numeric) into the single NotAPositiveInteger arm, so the only other distinct mode is the in-range-but-zero rejection. A new mode would be a deliberate change, and callers benefit from matching both arms without a wildcard.

Variants

Zero

The input parsed as 0, below the >= 1 worker-count floor.

Fields

input: String

The rejected input, verbatim (e.g. "0").

NotAPositiveInteger

The input was not auto and did not parse as a positive integer (non-numeric, negative, or overflowing).

Fields

input: String

The rejected input, verbatim.

Implementations

impl ParseNumJobsError

pub fn input(&self) -> &str

The rejected input that failed to parse as a NumJobs value.

Lets callers recover the offending string programmatically rather than scraping it out of the Display output.

Trait Implementations

impl Clone for ParseNumJobsError

fn clone(&self) -> ParseNumJobsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNumJobsError

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

Formats the value using the given formatter.

impl Display for ParseNumJobsError

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

Formats the value using the given formatter.

impl Eq for ParseNumJobsError

impl Error for ParseNumJobsError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ParseNumJobsError

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