CRFSuite trainer interface.

Fields

internal: *mut c_void

Pointer to the internal data (internal use only).

nref: c_int

Reference counter (internal use only).

addref: Option<unsafe extern "C" fn(trainer: *mut crfsuite_trainer_t) -> c_int>

Increment the reference counter.

trainer The pointer to this trainer instance.

Returns the reference count after this increment.

release: Option<unsafe extern "C" fn(trainer: *mut crfsuite_trainer_t) -> c_int>

Decrement the reference counter.

trainer The pointer to this trainer instance.

Returns the reference count after this operation.

params: Option<unsafe extern "C" fn(trainer: *mut crfsuite_trainer_t) -> *mut crfsuite_params_t>

Obtain the pointer to crfsuite_params_t interface.

trainer The pointer to this trainer instance.

Returns crfsuite_params_t* The pointer to crfsuite_params_t.

set_message_callback: Option<unsafe extern "C" fn(trainer: *mut crfsuite_trainer_t, user: *mut c_void, cbm: crfsuite_logging_callback)>

Set the callback function and user-defined data.

• trainer The pointer to this trainer instance.
• user The pointer to the user-defined data.
• cbm The pointer to the callback function.

train: Option<unsafe extern "C" fn(trainer: *mut crfsuite_trainer_t, data: *const crfsuite_data_t, filename: *const c_char, holdout: c_int) -> c_int>
