Stable lint categories. Match on the code rather than the message.

LintCode::as_str gives the name used in lint=allow(...), lint allow and the command-line tool’s diagnostics, which is stable too.

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.

OrphanPixel

A lone pixel on a flat area, close in lightness to the color around it, which reads as noise; or an opaque pixel that touches nothing at all.

Jaggy

Steps along a silhouette’s edge whose lengths jump, such as 1, 1, 3, 1, 1, where a clean line keeps one length or changes it gradually.

DoubleOutline

An outline two pixels thick at an L corner, where one diagonal step would do.

StrayAlpha

A lone translucent pixel in an otherwise opaque sprite: a leftover of smoothing.

NearDuplicateColor

Two keys of a palette, both used, whose colors are too close to tell apart.

FlatRamp

A ramp whose hue does not change from end to end: shades that only change in brightness look dull.

LowContrast

Neighbouring keys of a ramp too close in lightness to tell apart.

PillowShading

Shading that darkens toward the edges on every side, with no direction of light.

Banding

A line of a shade one pixel thick between a lighter and a darker one: shading stacked in parallel lines.

Mixel

A sprite drawn at 2×, 3× or 4× among sprites drawn at 1×.

TooManyColors

More colors than a sprite of its size reads well with.

InconsistentSize

A sprite of a set (an animation’s frames, a group) of another size than most.

InconsistentOutline

A sprite of a set with no outline, or another, when most have one; or with one when most have none.

InconsistentPalette

A sprite of a set drawn with a palette that is not a copy of the one most use.

InconsistentScale

A sprite of a set drawn at another pixel scale than most.

UnusedKey

A palette key that nothing uses.

ScreenBounds

An item falls partly outside its screen.

ScreenOverlap

Opaque pixels from multiple screen items overlap. Opt-in.

OffGrid

An item is not aligned to its screen’s declared grid.

BackgroundClipped

A background placement is fully clipped by its native layer or clip rectangle.

Implementations

impl LintCode

pub const ALL: [LintCode; 20]

Every code, in order.

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

The code’s stable name in snake_case, such as "orphan_pixel".

Trait Implementations

impl Clone for LintCode

fn clone(&self) -> Self
