## Example
```rust
use rknn_rs::prelude::*;
fn main() -> Result<(), Box> {
let rknn = Rknn::rknn_init("/home/kautism/SenseVoiceSmall-RKNN2/sense-voice-encoder.rknn")?;
rknn.input_set_slice(
0, // Set according to your input index
&flattened_input, // Borrowed input slice (no extra clone)
false, // Usually false, unless the model requires special handling
RknnTensorType::Float32,
RknnTensorFormat::NCHW,
)?;
let asr_output = rknn.outputs_get::()?;
// Do something with the data
Ok(())
}
```
