Struct SingleValueSurface 

pub struct SingleValueSurface<T> {
    pub size: Size,
    pub value: T,
}

A ‘surface’ that holds a single value, like a plain-colored rectangle.

Fields

size: Size

Surface size.

value: T

Stored value, likely a color.

Implementations

impl<T> SingleValueSurface<T>

pub const fn new(value: T, size: Size) -> Self

Construct a new surface.

pub fn value(&self) -> &T

Returns a reference to the underlying value.

pub fn value_mut(&mut self) -> &mut T

Returns a reference to the underlying value.

pub fn into_inner(self) -> T

Returns the underlying value.

Trait Implementations

impl<T: Clone> Clone for SingleValueSurface<T>

fn clone(&self) -> SingleValueSurface<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SingleValueSurface<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for SingleValueSurface<T>

fn eq(&self, other: &SingleValueSurface<T>) -> 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.
