Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl From<(u8, u8, u8)> for Color

fn from(_: (u8, u8, u8)) -> Color

Converts to this type from the input type.

impl From<(u8, u8, u8, u8)> for Color

fn from(_: (u8, u8, u8, u8)) -> Color

Converts to this type from the input type.

impl From<SDL_Color> for Color

fn from(raw: SDL_Color) -> Color

Converts to this type from the input type.

impl Hash for Color

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Into<SDL_Color> for Color

fn into(self) -> SDL_Color

Converts this type into the (usually inferred) input type.

impl PartialEq for Color

fn eq(&self, other: &Color) -> 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 Copy for Color

impl Eq for Color

impl StructuralPartialEq for Color
