Enum FailureClass 

pub enum FailureClass {
    CommandNotFound,
    Syntax,
    Encoding,
}

One class of shell failure a reader can act on.

Variants

CommandNotFound

The interpreter found no command by the name the line gave.

Syntax

The interpreter could not parse the line.

Encoding

The output held bytes that were not UTF-8, written down as U+FFFD.

Implementations

impl FailureClass

pub fn as_str(self) -> &'static str

The spelling a reader of the tally sees.

pub fn of( interpreter: &str, exit_code: i64, stdout: &str, stderr: &str, ) -> Option<Self>

Which class a shell result’s failure falls in, or None for a success and for a failure no rule recognises.

The exit code is read first, then the error ids that do not change with the display language, then the replacement character, and English text last: cmd prints its syntax errors in the language Windows is set to, so on another language they stay unclassified rather than this file carrying a second copy of Microsoft’s text.

Trait Implementations

impl Clone for FailureClass

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FailureClass

impl Debug for FailureClass

impl Eq for FailureClass

impl Ord for FailureClass

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for FailureClass

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for FailureClass

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
