Implementations

impl Affine2

pub const fn identity() -> Self

Creates a new value.

pub const fn translation(tx: f32, ty: f32) -> Self

Creates a new value.

pub const fn scaling(sx: f32, sy: f32) -> Self

Creates a new value.

pub fn validate(self) -> Result<()>

Validates this value.

pub fn determinant(self) -> Result<f32>

Returns determinant.

pub fn apply_point(self, point: Point2f) -> Point2f

Trait Implementations

impl Clone for Affine2

fn clone(&self) -> Affine2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Affine2

impl Debug for Affine2

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Affine2

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Affine2

fn eq(&self, other: &Affine2) -> 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 Serialize for Affine2

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
