Struct DiffusionOptions 

pub struct DiffusionOptions {
    pub model_id: Option<String>,
    pub device: Option<String>,
    pub width: Option<u32>,
    pub height: Option<u32>,
    pub num_inference_steps: Option<u32>,
    pub guidance_scale: Option<f32>,
    pub scheduler: DiffusionScheduler,
    pub cache_dir: Option<PathBuf>,
}

Options for constructing a DiffusionProvider.

All fields are optional and have sensible defaults. The scheduler defaults to DiffusionScheduler::EulerA and image dimensions default to 512x512.

Examples

use blazen_image_diffusion::{DiffusionOptions, DiffusionScheduler};

// Use defaults (512x512, EulerA scheduler, 20 steps)
let opts = DiffusionOptions::default();
assert_eq!(opts.scheduler, DiffusionScheduler::EulerA);

// Override specific fields
let opts = DiffusionOptions {
    width: Some(1024),
    height: Some(1024),
    num_inference_steps: Some(30),
    ..DiffusionOptions::default()
};

Fields

model_id: Option<String>

HuggingFace model repository ID (e.g. "stabilityai/stable-diffusion-2-1").

When None, a sensible default model will be selected in Phase 5.3.

device: Option<String>

Hardware device specifier string (e.g. "cpu", "cuda:0", "metal").

Accepts the same format strings as blazen_llm::Device::parse: "cpu", "cuda", "cuda:N", "metal".

When None, defaults to "cpu".

width: Option<u32>

Output image width in pixels.

When None, defaults to 512.

height: Option<u32>

Output image height in pixels.

When None, defaults to 512.

num_inference_steps: Option<u32>

Number of denoising steps to run.

More steps generally produce higher quality images at the cost of longer generation time. When None, defaults to 20.

guidance_scale: Option<f32>

Classifier-free guidance scale.

Higher values make the output more closely follow the prompt but may reduce diversity. Typical values range from 5.0 to 15.0. When None, defaults to 7.5.

scheduler: DiffusionScheduler

The noise scheduler to use during the diffusion process.

Defaults to DiffusionScheduler::EulerA.

cache_dir: Option<PathBuf>

Path to cache downloaded models.

When None, falls back to blazen-model-cache’s default cache directory ($BLAZEN_CACHE_DIR or ~/.cache/blazen/models).
