Enum ShadowStyle 

pub enum ShadowStyle {
    HalfBlock,
    Braille {
        density: f32,
    },
    MediumShade,
    Solid,
    Gradient {
        layers: u8,
    },
}

The rendering style for shadows.

Different styles offer tradeoffs between visual quality and terminal compatibility.

Variants

HalfBlock

Half-block characters (▐▄▌▀) for soft sub-cell shadows.

This is the default style and provides the best visual quality on most terminals. Uses foreground/background color blending for sub-cell precision.

Braille

Braille patterns (⣿) for dithered/density-based shadows.

Provides a 2x4 subpixel grid per cell for fine-grained density control. May not render correctly on all terminal fonts.

Fields

density: f32

Fill density from 0.0 (empty) to 1.0 (fully filled).

MediumShade

Medium shade character cells (▒) for textured full-cell shadows.

Uses foreground color with a fixed medium-density shade glyph. More visually pronounced than braille while preserving texture.

Solid

Solid color cells (space with background color).

The simplest shadow style - fills cells with solid background color. Maximum compatibility but no sub-cell precision.

Gradient

Multi-layer gradient shadow with decreasing intensity.

Creates a softer shadow effect by rendering multiple layers with progressively lighter colors.

Fields

layers: u8

Number of gradient layers (1-4). More layers = softer shadow, but uses more screen space.

Implementations

impl ShadowStyle

pub fn schema() -> SchemaNode

impl ShadowStyle

pub fn braille(density: f32) -> Self

Create a braille shadow with the specified density.

Arguments

• density - Fill density from 0.0 (empty) to 1.0 (fully filled). Values are clamped to this range.

pub fn gradient(layers: u8) -> Self

Create a gradient shadow with the specified number of layers.

Arguments

• layers - Number of gradient layers (clamped to 1-4).

pub fn name(&self) -> &'static str

Returns the shadow style name as a string.

pub fn terse_description(&self) -> &'static str

Returns a brief human-readable description of what this style does.

pub fn key_parameters(&self) -> Vec<(&'static str, String)>

Returns key parameters of this style for documentation purposes.

Trait Implementations

impl Clone for ShadowStyle

fn clone(&self) -> ShadowStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConfigSchema for ShadowStyle

fn schema() -> SchemaNode

impl Debug for ShadowStyle

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

Formats the value using the given formatter.

impl Default for ShadowStyle

fn default() -> ShadowStyle

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ShadowStyle

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ShadowStyle

fn eq(&self, other: &ShadowStyle) -> 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 Serialize for ShadowStyle

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ShadowStyle

impl StructuralPartialEq for ShadowStyle
