Enum AnimationChange 

#[non_exhaustive]
pub enum AnimationChange {
    None,
    ColorSameCategory,
    Shape,
}

Component of AnimationHint, describing the type of change predicted.

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.

None

Expect no changes.

ColorSameCategory

Expect that the block’s voxels’ colors will change, while remaining within the same OpacityCategory; that is, the alpha will remain 0, remain 1, or remain neither 0 nor 1.

Suggestion to renderers: prepare to update texturing without recomputing an otherwise identical mesh.

Shape

Expect that the block’s colors and shape will change; that is, at least some voxels’ alpha will move from one OpacityCategory to another.

Suggestion to renderers: use a rendering strategy which is shape-independent, or prepare to efficiently recompute the mesh (don’t merge with neighbors).

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for AnimationChange

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl BitOr for AnimationChange

type Output = AnimationChange

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl Clone for AnimationChange

fn clone(&self) -> AnimationChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnimationChange

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

Formats the value using the given formatter.

impl Hash for AnimationChange

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 PartialEq for AnimationChange

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