Struct Interpreter 

pub struct Interpreter<'lib> { /* private fields */ }

TFLite inference engine.

Owns its delegates and provides access to input/output tensors. Created via Interpreter::builder.

Implementations

impl<'lib> Interpreter<'lib>

pub fn builder(lib: &'lib Library) -> Result<InterpreterBuilder<'lib>>

Create a new InterpreterBuilder for configuring an interpreter.

Errors

Returns an error if TfLiteInterpreterOptionsCreate returns null.

pub fn allocate_tensors(&mut self) -> Result<()>

Re-allocate tensors after an input resize.

This must be called after Interpreter::resize_input and before Interpreter::invoke. Any previously obtained tensor slices or pointers are invalidated.

Errors

Returns an error if the C API returns a non-OK status.

pub fn resize_input(&mut self, input_index: usize, shape: &[i32]) -> Result<()>

Resize an input tensor’s dimensions.

After resizing, Interpreter::allocate_tensors must be called before inference can proceed.

Errors

Returns an error if the C API returns a non-OK status (e.g., the input index is out of range).

pub fn invoke(&mut self) -> Result<()>

Run model inference.

Errors

Returns an error if the C API returns a non-OK status.

pub fn inputs(&self) -> Result<Vec<Tensor<'_>>>

Get immutable views of all input tensors.

Errors

Returns an error if any input tensor pointer is null.

pub fn inputs_mut(&mut self) -> Result<Vec<TensorMut<'_>>>

Get mutable views of all input tensors.

Errors

Returns an error if any input tensor pointer is null.

pub fn outputs(&self) -> Result<Vec<Tensor<'_>>>

Get immutable views of all output tensors.

Errors

Returns an error if any output tensor pointer is null.

pub fn input_count(&self) -> usize

Returns the number of input tensors.

pub fn output_count(&self) -> usize

Returns the number of output tensors.

pub fn delegates(&self) -> &[Delegate]

Access all delegates owned by this interpreter.

pub fn delegate(&self, index: usize) -> Option<&Delegate>

Access a specific delegate by index.

Trait Implementations

impl Debug for Interpreter<'_>

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

Formats the value using the given formatter.

impl Drop for Interpreter<'_>

fn drop(&mut self)

Executes the destructor for this type.
