Struct Rendering 

pub struct Rendering<'a> {
    pub grain: Option<&'a GrainField>,
    pub emulsion: Option<&'a EmulsionBlur>,
    pub halation: Option<&'a Halation>,
    pub couplers: Option<&'a Couplers>,
    pub interimage: Option<&'a InterImage>,
    pub scanner: Option<&'a Scanner>,
    pub metering: Option<Metering>,
    pub backend: String,
}

Print what the development did, before any pixels are touched. What the render did beyond the model: the effects that were on, and who ran them. Grouped because a report function with eight arguments is a report function that grows one every phase.

Fields

grain: Option<&'a GrainField>

Grain, if it was on.

emulsion: Option<&'a EmulsionBlur>

The emulsion’s blur, if it was on.

halation: Option<&'a Halation>

Halation, if it was on.

couplers: Option<&'a Couplers>

DIR couplers, if they were on.

interimage: Option<&'a InterImage>

The cyan-sensitive layer’s inhibitor, if it was on — ADR 0018.

scanner: Option<&'a Scanner>

The scan’s texture and optics, if it was on.

metering: Option<Metering>

What the meter read, if the exposure was metered rather than named.

backend: String

Which backend did the work, already formatted.

Trait Implementations

impl Default for Rendering<'_>

fn default() -> Self

Returns the “default value” for a type.
