Enum Deposit 

pub enum Deposit {
    Max,
    Add,
}

How this frame’s light lands on the transformed past, from the [feedback] blend structural key (ADR-0048).

Variants

Max

accum = max(cur, prev * fade) — the engine’s only blend until ADR-0048, and still the default. Bounded by the source maximum.

Add

accum = cur + prev * fade — echoes that sum. Its geometric series is bounded by 1 / (1 - fade), which under the MAX_FADE = 0.98 ceiling is 50x, and it rolls off through ADR-0046’s tonemap rather than clipping. Only viable at all because the composite runs in linear light above 1.0.

Implementations

impl Deposit

pub const ALL: [Deposit; 2]

Both blends, for the load error’s “expected one of” listing and for the schema export, which renders this rather than restating it.

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

The canonical [feedback] blend name.

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

Parse a [feedback] blend value, or None if unknown.

Trait Implementations

impl Clone for Deposit

fn clone(&self) -> Deposit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Deposit

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

Formats the value using the given formatter.

impl Default for Deposit

fn default() -> Deposit

Returns the “default value” for a type.

impl PartialEq for Deposit

fn eq(&self, other: &Deposit) -> 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.
