Struct Delegate 

pub struct Delegate { /* private fields */ }

An external TFLite delegate for hardware acceleration.

Delegates are loaded from shared libraries that export the standard tflite_plugin_create_delegate / tflite_plugin_destroy_delegate entry points.

Examples

use edgefirst_tflite::{Delegate, DelegateOptions};

// Load delegate with default options
let delegate = Delegate::load("libvx_delegate.so")?;

// Load delegate with options
let delegate = Delegate::load_with_options(
    "libvx_delegate.so",
    &DelegateOptions::new()
        .option("cache_file_path", "/tmp/vx_cache")
        .option("device_id", "0"),
)?;

Implementations

impl Delegate

pub fn load(path: impl AsRef<Path>) -> Result<Self>

Load an external delegate from a shared library with default options.

Errors

Returns an error if the library cannot be loaded, required symbols are missing, or the delegate returns a null pointer.

pub fn load_with_options( path: impl AsRef<Path>, options: &DelegateOptions, ) -> Result<Self>

Load an external delegate with configuration options.

Errors

Returns an error if the library cannot be loaded, required symbols are missing, the delegate returns a null pointer, or any option key or value contains an interior NUL byte.

pub fn as_ptr(&self) -> *mut TfLiteDelegate

Returns the raw delegate pointer.

This is an escape hatch for advanced use cases that need direct FFI access to the delegate.

Trait Implementations

impl Debug for Delegate

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

Formats the value using the given formatter.

impl Drop for Delegate

fn drop(&mut self)

Executes the destructor for this type.
