Member Typedef Documentation

ShouldShowLocFn

using mlir::SourceMgrDiagnosticHandler::ShouldShowLocFn = llvm::unique_function<bool(Location)>

This type represents a functor used to filter out locations when printing a diagnostic.

It should return true if the provided location is okay to display, false otherwise. If all locations in a diagnostic are filtered out, the first location is used as the sole location. When deciding whether or not to filter a location, this function should not recurse into any nested location. This recursion is handled automatically by the caller.
