Struct HalCameraAdaptorFunctions 

pub struct HalCameraAdaptorFunctions {
    pub is_supported: unsafe extern "C" fn(*mut c_void, *const c_char) -> c_int,
    pub get_format_info: unsafe extern "C" fn(*mut c_void, *const c_char, *mut HalCameraAdaptorFormatInfo, usize) -> c_int,
}

Function pointers for the HAL Delegate Camera Adaptor API.

Loaded at runtime from the delegate shared library. Use HalCameraAdaptorFunctions::try_load to attempt loading.

The hal_delegate_t parameter (*mut c_void) is the TfLiteDelegate* cast to an opaque handle.

Fields

is_supported: unsafe extern "C" fn(*mut c_void, *const c_char) -> c_int

hal_camera_adaptor_is_supported — returns 1 if format is supported.

get_format_info: unsafe extern "C" fn(*mut c_void, *const c_char, *mut HalCameraAdaptorFormatInfo, usize) -> c_int

hal_camera_adaptor_get_format_info — fills info for the given format.

Implementations

impl HalCameraAdaptorFunctions

pub unsafe fn try_load(lib: &Library) -> Option<Self>

Attempt to load all HAL Camera Adaptor function pointers from a delegate library.

Returns None if any required symbol is missing.

Safety

The library must remain loaded for the lifetime of this struct.

Trait Implementations

impl Debug for HalCameraAdaptorFunctions

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

Formats the value using the given formatter.
