◆ tryStartCyclicPrint()

template<class AttrOrTypeT >

FailureOr<CyclicPrintReset> mlir::AsmPrinter::tryStartCyclicPrint ( AttrOrTypeT attrOrType )

inline

Attempts to start a cyclic printing region for attrOrType.

A cyclic printing region starts with this call and ends with the destruction of the returned CyclicPrintReset. During this time, calling tryStartCyclicPrint with the same attribute in any printer will lead to returning failure.

This makes it possible to break infinite recursions when trying to print cyclic attributes or types by printing only immutable parameters if nested within itself.
