}
|
|
|
|
b, err := ml.GenconfigMarshal(cfg)
|

## Notas
|
|
|
|
### Formato canonico y compatibilidad con Python
|
|
|
|
`GenconfigMarshal` usa `json.MarshalIndent(cfg, "", " ")`. El formato resultante es identico al que produce Python con `model.model_dump_json()` o `json.dumps(data, indent=2)` cuando `sort_keys=False`:
|
|
|
|
- Keys en orden de declaracion del struct (no alfabetico).
|
|
- Indent de 2 espacios, sin trailing whitespace.
|
|
- Campos omitempty ausentes si zero: `negative_prompt` ausente si `""`, `loras` ausente si `[]`, `clip_skip` ausente si `nil`.
|
|
|
|
### Keys JSON (snake_case obligatorio)
|
|
|
|
| Campo Go | Key JSON |
|
|
|---|---|
|
|
| `Prompt` | `"prompt"` |
|
|
| `NegativePrompt` | `"negative_prompt"` |
|
|
| `Seed` | `"seed"` |
|
|
| `Steps` | `"steps"` |
|
|
| `CfgScale` | `"cfg_scale"` |
|
|
| `Sampler` | `"sampler"` |
|
|
| `Width` | `"width"` |
|
|
| `Height` | `"height"` |
|
|
| `Model.ModelType` | `"model_type"` |
|
|
| `Model.Quantization` | `"quantization"` |
|
|
| `ClipSkip` | `"clip_skip"` |
|
|
|
|
### Por que impure
|
|
|
|
Los errores de `json.Unmarshal` son errores de parsing del input externo, no de I/O, pero se modelan como `(T, error)` para forzar manejo explicito en el caller. Marcado `impure` con `error_type: error_go_core` por convencion del registry.
