Tuple Fields

0: [Align; 2]

Implementations

impl Align2

pub const LEFT_BOTTOM: Self = _

pub const LEFT_CENTER: Self = _

pub const LEFT_TOP: Self = _

pub const CENTER_BOTTOM: Self = _

pub const CENTER_CENTER: Self = _

impl Align2

pub fn x(self) -> Align

Returns an alignment by the X (horizontal) axis

pub fn y(self) -> Align

Returns an alignment by the Y (vertical) axis

pub fn to_sign(self) -> Vec2

-1, 0, or +1 for each axis

pub fn anchor_rect(self, rect: Rect) -> Rect

Used e.g. to anchor a piece of text to a part of the rectangle. Give a position within the rect, specified by the aligns

pub fn anchor_size(self, pos: Pos2, size: Vec2) -> Rect

Use this anchor to position something around pos, e.g. Self::RIGHT_TOP means the right-top of the rect will end up at pos.

pub fn align_size_within_rect(self, size: Vec2, frame: Rect) -> Rect

e.g. center a size within a given frame

pub fn pos_in_rect(self, frame: &Rect) -> Pos2

Returns the point on the rect’s frame or in the center of a rect according to the alignments of this object.

Trait Implementations

impl Clone for Align2

fn clone(&self) -> Align2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Align2

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

Formats the value using the given formatter.

impl Hash for Align2

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 Index<usize> for Align2

type Output = Align

The returned type after indexing.

fn index(&self, index: usize) -> &Align

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Align2

fn index_mut(&mut self, index: usize) -> &mut Align

Performs the mutable indexing (container[index]) operation.

impl PartialEq for Align2

fn eq(&self, other: &Align2) -> 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.
