Enum Warp 

pub enum Warp {
    None,
    Swirl,
    Ripple,
    Fisheye,
}

The curated procedural warp an accumulation resamples its past through, from the [feedback] warp structural key (ADR-0048).

Load-time, not bindable, by [curve] family’s reasoning: a warp kind is a shader path, not a quantity, and ADR-0021 already rejected bindable discrete indexes for the flicker/hard-cut class of reasons. Its strength is the ordinary bindable fb_warp, which is where a preset puts the audio.

The family is deliberately small (ADR-0048 Alternative A): an author-defined per-pixel warp is a grammar-to-WGSL translator and a per-preset pipeline compile, and it should be decided as that rather than smuggled in as a stage option.

Variants

None

No procedural warp — the affine alone. The default, and the identity.

Swirl

A vortex: the past rotates about the feedback centre by an angle that falls off with radius, so the middle spins faster than the rim.

Ripple

Concentric standing waves in radius — the past breathes in rings.

Fisheye

A radial magnification that grows with radius: the periphery is drawn in (positive fb_warp) or pushed out (negative).

Implementations

impl Warp

pub const ALL: [Warp; 4]

Every kind, in the order the error message lists them.

pub fn from_name(name: &str) -> Option<Self>

Parse a [feedback] warp value, or None if unknown (a load error — the preset is rejected rather than silently rendering unwarped).

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

The canonical name — the exact string from_name accepts. The two are inverses and the one place the mapping lives.

Trait Implementations

impl Clone for Warp

fn clone(&self) -> Warp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Warp

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

Formats the value using the given formatter.

impl Default for Warp

fn default() -> Warp

Returns the “default value” for a type.

impl PartialEq for Warp

fn eq(&self, other: &Warp) -> 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 Copy for Warp

impl Eq for Warp

impl StructuralPartialEq for Warp
