Struct GradientButtonDecoration 

pub struct GradientButtonDecoration { /* private fields */ }

A ButtonDecoration painting gradient fill/overlay/outline/foreground layers — the reference’s M3EButtonDecoration gradient quadruple (backgroundGradient/overlayGradient/outlineGradient/ foregroundGradient, m3e_button_decoration.dart:83-:92) realized against this crate’s ButtonDecoration seam. See the module docs for the full gradient-class inventory and scope notes.

Implementations

impl GradientButtonDecoration

pub fn new() -> Self

A decoration with no layer configured — every hook falls through to DecorationOutcome::Skipped/None until a layer is set.

pub fn background(self, property: GradientProperty) -> Self

Set the container fill gradient (backgroundGradient).

pub fn foreground(self, property: GradientProperty) -> Self

Set the label ink gradient (foregroundGradient). See ButtonDecoration::foreground_brush for the label-only scope note.

pub fn overlay(self, property: GradientProperty) -> Self

Set the interaction state-layer gradient (overlayGradient).

pub fn outline(self, property: GradientProperty) -> Self

Set the hairline gradient (outlineGradient).

Trait Implementations

impl ButtonDecoration for GradientButtonDecoration

fn paint_fill( &self, surface: &ButtonSurface, scene: &mut dyn PaintScene, ) -> DecorationOutcome

Paint the container fill. DecorationOutcome::Painted suppresses the core’s own solid fill.

fn paint_overlay( &self, surface: &ButtonSurface, scene: &mut dyn PaintScene, ) -> DecorationOutcome

Paint an overlay above the fill. DecorationOutcome::Painted suppresses the core’s own interaction state layer — mirroring m3e_button_style.dart:47, where a gradient overlay forces overlayColor to transparent so the two never stack.

fn paint_outline( &self, surface: &ButtonSurface, scene: &mut dyn PaintScene, ) -> DecorationOutcome

Paint the outline. DecorationOutcome::Painted suppresses the core’s own hairline.

fn foreground_brush(&self, surface: &ButtonSurface) -> Option<Brush>

Resolve a Brush (solid or gradient) to paint the label’s ink with, replacing the core’s own per-variant/per-state solid content color — where the reference’s foregroundGradient attaches (m3eGradientForegroundBuilder, m3e_button_content.dart:157).

impl Clone for GradientButtonDecoration

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for GradientButtonDecoration

fn default() -> Self

Returns the “default value” for a type.
