Classes
struct	xgboost::collective::detail::ResultImpl

struct	xgboost::collective::Result
	An error type that's easier to handle than throwing dmlc exception. We can record and propagate the system error code. More...

Namespaces
	xgboost
	Learner interface that integrates objective, gbm and evaluation together. This is the user facing XGBoost training module.

	xgboost::collective

	xgboost::collective::detail

Functions
std::string	xgboost::collective::detail::MakeMsg (std::string &&msg, char const *file, std::int32_t line)

Result	xgboost::collective::operator+ (Result &&lhs, Result &&rhs)

auto	xgboost::collective::Success () noexcept(true)
	Return success. More...

auto	xgboost::collective::Fail (std::string msg, char const *file=__builtin_FILE(), std::int32_t line=__builtin_LINE())
	Return failure. More...

auto	xgboost::collective::Fail (std::string msg, std::error_code errc, char const *file=__builtin_FILE(), std::int32_t line=__builtin_LINE())
	Return failure with `errno`. More...

auto	xgboost::collective::Fail (std::string msg, Result &&prev, char const *file=__builtin_FILE(), std::int32_t line=__builtin_LINE())
	Return failure with a previous error. More...

auto	xgboost::collective::Fail (std::string msg, std::error_code errc, Result &&prev, char const *file=__builtin_FILE(), std::int32_t line=__builtin_LINE())
	Return failure with a previous error and a new `errno`. More...
