Struct CrossfadeParams 

pub struct CrossfadeParams {
    pub spread: f32,
    pub scale: Length,
    pub softness: f32,
    pub seed: f32,
}

crossfade: a noise-staggered two-input blend. A smooth fbm value-noise field gives each pixel a stagger offset (n * spread) so blob-shaped regions cross-dissolve earlier than others; each pixel then fades linearly over a softness-wide window of the progress range. spread: 0 is the plain uniform mix(from, to, progress) (bit-exact — the shader fast-paths it), and noise is ON by default.

A single pass, packed as params[0] = (spread, scale_logical_px, softness, seed); resolve prepends the Length px validation for scale before delegating to resolve_single_pass (the default would skip it).

Fields

spread: f32

0..1 stagger amount; 0 is the plain uniform crossfade.

scale: Length

Noise feature size in logical px.

softness: f32

0..1 local fade window (fraction of the progress range).

seed: f32

Re-rolls the noise pattern (domain offset).

Trait Implementations

impl Clone for CrossfadeParams

fn clone(&self) -> CrossfadeParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CrossfadeParams

impl Debug for CrossfadeParams

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

Formats the value using the given formatter.

impl Default for CrossfadeParams

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CrossfadeParams

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CrossfadeParams

fn eq(&self, other: &CrossfadeParams) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl ReactFilter for CrossfadeParams

const NAME: &'static str = "crossfade"

The wire name in a FilterUse (camelCase, e.g. "hueRotate").

const IS_MORPH: bool = true

Whether this is a two-input morph filter (a morphFilter name). The two families are separate: morph filters cannot appear in filter/backdropFilter chains and regular filters cannot be morphFilter names — enforced at resolve time per chain surface, and mirrored in the generated TypeScript (BevyFilters vs BevyMorphFilters). Set by #[react_morph_filter]; regular filters keep the default.

fn shader(assets: &AssetServer) -> Handle<Shader>

The pass shader. Lazy: called inside resolve, never at registration time, so registering filters needs no AssetServer.

fn outset(&self) -> Result<f32, String>

Extra logical px the effect bleeds outside the node’s rect (blur reach). Identity for most filters. Fallible so params that cannot yield a px value (blur’s non-px radius) reject instead of silently packing 0.0.

fn pack(&self) -> (Vec<Vec4>, Arc<[ParamSlot]>)

Pack the params into the uniform Vec4 array plus the layout saying where each named param landed. Length params pack their logical-px value (see ParamSlot).

fn resolve( &self, assets: &AssetServer, ) -> Result<Vec<ResolvedFilterPass>, String>

Resolve into render passes. The default builds one pass straight from pack (see resolve_single_pass); multi-pass effects (blur: H then V) override it. Passes come back with wire_index: 0 — resolve fns don’t know their chain position; the chain resolver rewrites it (see ResolvedFilterPass::wire_index).

const USES_TIME: bool = false

Whether the effect is time-driven (must re-render every frame even with static params). None of the built-ins are.

fn identity_params() -> Option<Value>

The params JSON of this filter’s identity invocation (no visual effect), if it has one — brightness/contrast/saturate amount: 1, grayscale/sepia/invert amount: 0 (their identity is 0, NOT the CSS shorthand default of 1), blur radius: 0, hueRotate angle: 0.

impl ReactMorphFilter for CrossfadeParams

impl StructuralPartialEq for CrossfadeParams

impl TS for CrossfadeParams

const DOCS: Option<&'static str>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

type WithoutGenerics = CrossfadeParams

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or (). The only requirement for these dummy types is that EXPORT_TO must be None.

fn ident() -> String

Identifier of this type, excluding generic parameters.

fn name() -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete() -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl() -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline() -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened() -> String

Flatten a type declaration.
This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<&'static Path>

Returns the output path to where T should be exported.
The returned path does not include the base directory from TS_RS_EXPORT_DIR.

fn visit_dependencies(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all dependency of this type.

fn dependencies() -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_all_to(out_dir: impl AsRef<Path>) -> Result<(), ExportError>

where Self: 'static,

Manually export this type into the given directory, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_to_string() -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String.
This function does not format the output, even if the format feature is enabled.

fn default_output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
