An identifier for one of the 14 hard accessibility rules. Each variant carries its own doc comment describing the specific constraint the rule enforces.

Variants

AsciiOnly

R1: Every byte is ASCII printable (0x20–0x7E) or \n.

LineLength

R2: Every line is ≤ 80 characters.

NoAnsi

R3: No ANSI escape sequences.

ErrorPrefix

R4: Error lines begin with Error:.

WarningPrefix

R5: Warning lines begin with Warning:.

ConfirmOnSet

R6: Mutating commands confirm success. (Covered by per-command unit tests; not a line-level rule.)

ListCountSummary

R7: Lists end with a count summary. (Covered by per-command unit tests.)

LabelColonValue

R8: Labels end with a colon before their values.

BooleanWords

R9: Booleans render as on/off, never true/false or 1/0.

NoNakedPrint

R10: No print! without a trailing newline. (Static grep rule.)

NoCursorMoves

R11: No cursor-move sequences or spinners. (Static grep rule.)

UnitsSpelledOut

R12: Numeric units spelled out (megahertz, watts, etc.).

NoAdHocTimestamps

R13: No ad-hoc [HH:MM:SS] timestamps. (Static grep rule.)

StdoutStderrSeparation

R14: User output to stdout, diagnostics to stderr. (Static grep rule.)

Implementations

impl Rule

pub const fn id(self) -> &'static str

Short identifier used in error messages and the compliance report: "R1", "R2", etc.

pub const fn description(self) -> &'static str

Human-readable summary of the rule, suitable for the report printed by the check subcommand.

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

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

Formats the value using the given formatter.

impl Ord for Rule

fn cmp(&self, other: &Rule) -> 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.

impl PartialEq for Rule

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

impl PartialOrd for Rule

fn partial_cmp(&self, other: &Rule) -> 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.
