Struct Zoom 

pub struct Zoom { /* private fields */ }

Data for Modifier::Zoom, describing a portion of the original block that is scaled up to become the whole block.

Design note: This is a struct separate from Modifier so that it can have a constructor accepting only valid bounds.

Implementations

impl Zoom

pub fn new(scale: Resolution, offset: GridPoint) -> Self

Construct a Zoom which enlarges the original block’s voxels by scale and selects the region of them whose lower corner is offset * scale.

Panics if any of offset’s components are out of bounds, i.e. less than 0 or greater than scale - 1.

pub fn scale(&self) -> Resolution

Scale factor to zoom in by.

pub fn offset(&self) -> GridPoint

Which portion of the block/space will be used, specified in terms of an offset in the grid of zoomed blocks (that is, this will have coordinates between 0 and scale - 1).

Trait Implementations

impl<'a> Arbitrary<'a> for Zoom

Available on crate feature arbitrary only.

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

Generate an arbitrary value of Self from 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 arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

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

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 Clone for Zoom

fn clone(&self) -> Zoom

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Zoom

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

Formats the value using the given formatter.

impl From<Zoom> for Modifier

fn from(value: Zoom) -> Self

Converts to this type from the input type.

impl Hash for Zoom

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 Zoom

fn eq(&self, other: &Zoom) -> 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 VisitHandles for Zoom

fn visit_handles(&self, _visitor: &mut dyn HandleVisitor)

For each Handle contained within self that is reachable without traversing another Handle, call visitor with a reference to it.

impl Eq for Zoom
