Structure of external MlirPass callbacks. All callbacks are required to be set unless otherwise specified.

Fields

construct: Option<unsafe extern "C" fn(userData: *mut c_void)>

This callback is called from the pass is created. This is analogous to a C++ pass constructor.

destruct: Option<unsafe extern "C" fn(userData: *mut c_void)>

This callback is called when the pass is destroyed This is analogous to a C++ pass destructor.

initialize: Option<unsafe extern "C" fn(ctx: MlirContext, userData: *mut c_void) -> MlirLogicalResult>

This callback is optional. The callback is called before the pass is run, allowing a chance to initialize any complex state necessary for running the pass. See Pass::initialize(MLIRContext *).

clone: Option<unsafe extern "C" fn(userData: *mut c_void) -> *mut c_void>

This callback is called when the pass is cloned. See Pass::clonePass().

run: Option<unsafe extern "C" fn(op: MlirOperation, pass: MlirExternalPass, userData: *mut c_void)>

This callback is called when the pass is run. See Pass::runOnOperation().
