Comparison of not_null's works for raw pointers, but causes compilation errors for smart pointers such as std::shared_ptr. This makes difficult storing not_null<shared_ptr> in a set or using them as keys in a map. { gsl::not_null<std::shared_ptr<int>>p(std::make_shared<int>(42)...
The Guidelines Support Library (GSL) contains functions and types that are suggested for use by theC++ Core Guidelinesmaintained by theStandard C++ Foundation. The library includes types likeowner<>,not_null<>,span<>,string_spanandothers. gsl-literecognizes when it is compiled for the CUDA platf...

是指在R语言中使用gsl包时可能出现的错误。gsl是GNU Scientific Library的简称,是一个开源的数值计算库,提供了丰富的数学和科学计算函数。 错误概念:当在R中使用gsl包时,可能会遇到以下错误: "Error: package 'gsl' is not available":表示gsl包未安装或未被正确加载。 "Error: package or namespace load faile...
