Struct graphene::Vec2

pub struct Vec2 { /* private fields */ }

A structure capable of holding a vector with two dimensions, x and y.

The contents of the Vec2 structure are private and should never be accessed directly.

Trait Implementations

impl Clone for Vec2

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Vec2

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

Formats the value using the given formatter.

impl Default for Vec2

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for Vec2

type ParamSpec = ParamSpecBoxed

type SetValue = Vec2

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, Vec2>

impl PartialEq for Vec2

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
