Enum Lint 

#[non_exhaustive]
pub enum Lint {
    RawColor,

    ManyPrimaryButtons,
    StateInBody,
    BlockingInBody,

    AllowWithoutReason,
    UnknownLint,
}

A rule ravenrs-lint checks. Every rule is deny unless the configuration lowers it, and lowering one to allow needs a reason.

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.

RawColor

A Color value written in the interface (Color::rgb, Color::WHITE, Color { .. }). It looks right in one theme and wrong in the others. Defining a theme (Theme { .. }, Palette { .. } or a function returning one) is where colors belong, so it is left alone, and so are the pixels of a picture drawn with ImageData::from_fn.

RawFontSize

.font_size(..): text sizes come from TextStyle steps. A printed report’s Style is measured in points and left alone.

OffGridSpacing

.padding, .spacing, .gap or Insets with a literal that is not a multiple of 4.

ButtonWithoutVerb

A Button caption that does not start with a verb.

IconButtonWithoutLabel

An IconButton with no .label(..): screen readers would only say the icon’s name.

ManyPrimaryButtons

More than one primary Button in one function. Button is primary unless .style(..) says otherwise.

StateInBody

State::new inside body or build, which run on every rebuild and start it over.

BlockingInBody

Files, processes, sleeping or blocking network calls inside body or build, which freeze the window on every rebuild.

OversizedFile

A source file longer than max-file-lines (600 by default).

AllowWithoutReason

A ravenrs-lint: allow(..) comment that does not say why.

UnknownLint

A ravenrs-lint: allow(..) comment naming a rule that does not exist.

Implementations

impl Lint

pub const ALL: &'static [Lint]

Every rule, in the order they are documented.

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

The name used in diagnostics, configuration and allow(..) comments.

pub fn from_name(name: &str) -> Option<Lint>

The rule called name, if there is one.

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

One line on what the rule protects.

Trait Implementations

impl Clone for Lint

fn clone(&self) -> Lint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Lint

impl Debug for Lint

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

Formats the value using the given formatter.

impl Eq for Lint

impl Hash for Lint

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 Lint

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Lint

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