Struct ModelPaths 

pub struct ModelPaths {

    pub transformer: PathBuf,
    pub transformer_shards: Vec<PathBuf>,
    pub vae: PathBuf,
    pub spatial_upscaler: Option<PathBuf>,
    pub temporal_upscaler: Option<PathBuf>,
    pub distilled_lora: Option<PathBuf>,

    pub clip_encoder_2: Option<PathBuf>,
    pub clip_tokenizer_2: Option<PathBuf>,
    pub text_encoder_files: Vec<PathBuf>,
    pub text_tokenizer: Option<PathBuf>,
    pub decoder: Option<PathBuf>,
}

Resolved model file paths. For diffusion models, transformer and vae are always required. For upscaler models, only transformer (weights) is required; vae is empty. For utility models, only transformer is required; vae may be empty. Other paths are optional — each engine validates what it needs at load time.

Fields

transformer: PathBuf

transformer_shards: Vec<PathBuf>

Multi-shard transformer paths (Z-Image BF16); empty means use single transformer

vae: PathBuf

spatial_upscaler: Option<PathBuf>

temporal_upscaler: Option<PathBuf>

distilled_lora: Option<PathBuf>

t5_encoder: Option<PathBuf>

clip_encoder: Option<PathBuf>

t5_tokenizer: Option<PathBuf>

clip_tokenizer: Option<PathBuf>

clip_encoder_2: Option<PathBuf>

CLIP-G / OpenCLIP encoder (SDXL only)

clip_tokenizer_2: Option<PathBuf>

CLIP-G / OpenCLIP tokenizer (SDXL only)

text_encoder_files: Vec<PathBuf>

Generic text encoder shard paths (Qwen3 for Z-Image)

text_tokenizer: Option<PathBuf>

Generic text encoder tokenizer (Qwen3 for Z-Image)

decoder: Option<PathBuf>

Stage B decoder weights (Wuerstchen only)

Implementations

impl ModelPaths

pub fn resolve(model_name: &str, config: &Config) -> Option<Self>

Resolve paths for a model. Checks config, then env vars. Returns None if transformer and VAE paths can’t be resolved. All other paths are optional (depend on model family).

Trait Implementations

impl Clone for ModelPaths

fn clone(&self) -> ModelPaths

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelPaths

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

Formats the value using the given formatter.
