Enum ShadowCompositeMode 

pub enum ShadowCompositeMode {
    GlyphOverlay,
    GradeUnderlying,
}

Determines how the compositor applies shadow data onto destination cells.

Shadow geometry, masks, offsets, and progress timing are shared across all compositing modes. The mode controls only the final blending step.

Backward Compatibility

The default is GlyphOverlay, which preserves the existing shadow rendering behavior. Switching to GradeUnderlying changes only the blend step, not the shadow geometry pipeline.

Variants

GlyphOverlay

Classic shadow rendering: shadow cells overwrite destination cells with shadow glyphs and colors.

This is the original behavior and remains the default for backward compatibility.

GradeUnderlying

Destination-preserving shadow: leaves destination glyphs and modifiers intact while applying color grading (dim, desaturate, tint) to the shadow region.

Use this mode with ShadowGradeConfig to control grading intensity. The ShadowConfig::with_dramatic_grade builder provides a recommended visible preset.

pub fn schema() -> SchemaNode

Trait Implementations

impl Clone for ShadowCompositeMode

fn clone(&self) -> ShadowCompositeMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConfigSchema for ShadowCompositeMode

fn schema() -> SchemaNode

impl Debug for ShadowCompositeMode

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

Formats the value using the given formatter.

impl Default for ShadowCompositeMode

fn default() -> ShadowCompositeMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ShadowCompositeMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ShadowCompositeMode

fn eq(&self, other: &ShadowCompositeMode) -> 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 ShadowCompositeMode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
