Enum FormatRule 

#[non_exhaustive]
pub enum FormatRule {
    Imports,
    Layout,
    Spacing,
    SyntaxNormalization,
}

A discrete formatter rule that can be enabled or disabled.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Imports

Organize import declarations into formatter-defined groups.

Layout

Apply AST-guided structural layout and indentation.

Spacing

Normalize whitespace gaps and type-annotation colon spacing.

SyntaxNormalization

Rewrite layout forms into canonical multiline shapes.

Implementations

impl FormatRule

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

Stable kebab-case CLI/config id for this formatter rule.

Trait Implementations

impl Clone for FormatRule

fn clone(&self) -> FormatRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FormatRule

impl Debug for FormatRule

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

Formats the value using the given formatter.

impl Display for FormatRule

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

Formats the value using the given formatter.

impl Eq for FormatRule

impl FromStr for FormatRule

type Err = FormatRuleParseError

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for FormatRule

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for FormatRule

fn cmp(&self, other: &FormatRule) -> 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 FormatRule

fn eq(&self, other: &FormatRule) -> 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 FormatRule

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