tensorstore::ChainResult

#include "tensorstore/util/result.h"

template <typename T> auto tensorstore::ChainResult(T&& arg);

template <typename T, typename Func0, typename... Func> auto tensorstore::ChainResult(T&& arg, Func0&& func0, Func&&... func);

Applies a sequence of functions, which may optionally return Result-wrapped values, to an optionally Result-wrapped value.

For example:

float func1(int x);
Result<std::string> func2(float x);
bool func3(std::string_view x);

Result<bool> y1 = ChainResult(Result<int>(3), func1, func2, func3);
Result<bool> y2 = ChainResult(3, func1, func2, func3);
