Struct FormatOption 

pub struct FormatOption {
    pub descriptor: PixelDescriptor,
    pub consumer_cost: ConversionCost,
}

A supported format with optional consumer-provided cost override.

Use this with best_match_with when the consumer can handle some formats more efficiently than the default conversion path.

Example

A JPEG encoder with a fast internal f32→u8 path:

use zenpixels::{FormatOption, ConversionCost};
use zenpixels::PixelDescriptor;

let options = &[
    FormatOption::from(PixelDescriptor::RGB8_SRGB),     // native, zero cost
    FormatOption::with_cost(
        PixelDescriptor::RGBF32_LINEAR,
        ConversionCost::new(5, 0),  // fast fused path, no extra loss
    ),
];

Fields

descriptor: PixelDescriptor

The pixel format the consumer can accept.

consumer_cost: ConversionCost

Additional cost the consumer incurs to handle this format after we deliver it. Zero for native formats.

Implementations
