nros::Result Class Reference

#include <result.hpp>

Public Member Functions
ErrorCode	code () const
	Get the underlying error code.
bool	ok () const
	Returns true if the operation succeeded.
	operator bool () const
	Explicit bool conversion — allows if (result) { ... }.
int32_t	raw () const
	Get the raw integer code (for FFI interop).
constexpr	Result ()
	Default-construct a success.
constexpr	Result (ErrorCode code)
	Construct from a typed code.
constexpr	Result (int32_t raw)
	Construct from a raw FFI return value (int32_t).

Static Public Member Functions
static constexpr Result	success ()
	Named constructors.

Detailed Description

Result type for fallible operations.

This replaces exceptions in freestanding C++. Use the NROS_TRY macro for early return on error.

Constructor & Destructor Documentation

Result() [1/3]

constexpr nros::Result::Result ( )

inlineconstexpr

Default-construct a success.

Result() [2/3]

constexpr nros::Result::Result ( ErrorCode  code )

inlineconstexpr

Construct from a typed code.

Result() [3/3]

constexpr nros::Result::Result ( int32_t  raw )

inlineconstexpr

Construct from a raw FFI return value (int32_t).
