Struct RGBA

pub struct RGBA { /* private fields */ }

GLib type: Inline allocated boxed type with stack copy semantics.

Implementations

impl RGBA

pub fn as_ptr(&self) -> *mut GdkRGBA

pub unsafe fn from_glib_ptr_borrow<'a>(ptr: *const GdkRGBA) -> &'a Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut<'a>(ptr: *mut GdkRGBA) -> &'a mut Self

Borrows the underlying C value mutably.

impl RGBA

pub fn is_clear(&self) -> bool

pub fn is_opaque(&self) -> bool

pub fn to_str(&self) -> GString

impl RGBA

pub const BLACK: RGBA

pub const BLUE: RGBA

pub const GREEN: RGBA

pub const RED: RGBA

pub const WHITE: RGBA

pub const TRANSPARENT: RGBA

pub const fn new(red: f32, green: f32, blue: f32, alpha: f32) -> Self

pub const fn with_red(self, red: f32) -> Self

Creates an owned RGBA like self but with the given red value.

Example

let rgba = RGBA::new(1.0, 1.0, 1.0, 1.0);
assert_eq!(rgba.with_red(0.5), RGBA::new(0.5, 1.0, 1.0, 1.0));

pub const fn with_green(self, green: f32) -> Self

Creates an owned RGBA like self but with the given green value.

Example

let rgba = RGBA::new(1.0, 1.0, 1.0, 1.0);
assert_eq!(rgba.with_green(0.5), RGBA::new(1.0, 0.5, 1.0, 1.0));

pub const fn with_blue(self, blue: f32) -> Self

Creates an owned RGBA like self but with the given blue value.

Example

let rgba = RGBA::new(1.0, 1.0, 1.0, 1.0);
assert_eq!(rgba.with_blue(0.5), RGBA::new(1.0, 1.0, 0.5, 1.0));

pub const fn with_alpha(self, alpha: f32) -> Self

Creates an owned RGBA like self but with the given alpha value.

Example

let rgba = RGBA::new(1.0, 1.0, 1.0, 1.0);
assert_eq!(rgba.with_alpha(0.5), RGBA::new(1.0, 1.0, 1.0, 0.5));

pub fn builder() -> RGBABuilder

Creates a new builder-pattern struct instance to construct RGBA objects.

This method returns an instance of RGBABuilder which can be used to create RGBA objects.

pub fn red(&self) -> f32

pub fn set_red(&mut self, red: f32)

pub fn green(&self) -> f32

pub fn set_green(&mut self, green: f32)

pub fn blue(&self) -> f32

pub fn set_blue(&mut self, blue: f32)

pub fn alpha(&self) -> f32

pub fn set_alpha(&mut self, alpha: f32)

pub fn parse(s: impl IntoGStr) -> Result<RGBA, BoolError>

Trait Implementations

impl Clone for RGBA

fn clone(&self) -> Self

Copies the inline boxed type by value with the type-specific copy function.

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

Performs copy-assignment from source.

impl Debug for RGBA

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

Formats the value using the given formatter.

impl Display for RGBA

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

Formats the value using the given formatter.

impl FromStr for RGBA

type Err = BoolError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl HasParamSpec for RGBA

type ParamSpec = ParamSpecBoxed

type SetValue = RGBA

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for RGBA

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 PartialEq for RGBA

fn eq(&self, other: &Self) -> 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 StaticType for RGBA

fn static_type() -> Type

Returns the type identifier of Self.

impl Copy for RGBA

impl Eq for RGBA
