attachDiagnosticHandler()

nb::object PyMlirContext::attachDiagnosticHandler

(

nanobind::object

callback

)

Attaches a Python callback as a diagnostic handler, returning a registration object (internally a PyDiagnosticHandler).

Definition at line 721 of file IRCore.cpp.

References get(), mlir::python::PyDiagnostic::invalidate(), mlirContextAttachDiagnosticHandler(), mlirLogicalResultFailure(), and mlirLogicalResultSuccess().

contextEnter()

nb::object PyMlirContext::contextEnter ( nanobind::object  context )

static

Enter and exit the context manager.

contextExit()

void PyMlirContext::contextExit	(	const nanobind::object &	excType,

		const nanobind::object &	excTb
	)

Definition at line 715 of file IRCore.cpp.

References mlir::python::PyThreadContextEntry::popContext().

createFromCapsule()

nb::object PyMlirContext::createFromCapsule ( nanobind::object  capsule )

static

Creates a PyMlirContext from the MlirContext wrapped by a capsule.

Note that PyMlirContext instances are uniqued, so the returned object may be a pre-existing object. Ownership of the underlying MlirContext is taken by calling this function.
