Struct OnnxEmbeddingConfig 

pub struct OnnxEmbeddingConfig {
    pub model_path: PathBuf,
    pub tokenizer_path: PathBuf,
    pub model_name: String,
    pub dimensions: usize,
    pub max_sequence_length: usize,
    pub batch_size: usize,
}

ONNX-specific configuration.

Only used when EmbeddingConfig::provider is Onnx or Fastembed. All other providers use the top-level EmbeddingConfig fields only.

Fields

model_path: PathBuf

Path to ONNX model file (.onnx)

tokenizer_path: PathBuf

Path to tokenizer.json file

model_name: String

Model name for logging/identification and auto-download selection

dimensions: usize

Embedding dimensions (must match model output)

max_sequence_length: usize

Maximum sequence length in tokens (truncate if longer)

batch_size: usize

Batch size for ONNX inference (max texts per inference call)
