    const error &
) = default

Returns:

A reference to this instance.

function operator=

Move assignment operator.

    error &&
) = default

Returns:

A reference to this instance.

function throw_exception

Panics on unrecoverable errors inside destructors etc.

void mdbx::error::throw_exception () const

Exception:

The corresponding mdbx::exception if the error is a failure.

function what

The pointer to a constant string with the error message.

Public Static Functions Documentation

function success_or_throw

Throws the corresponding exception if the code is a failure.

static inline void mdbx::error::success_or_throw (
    int error_code
)

Parameters:

error_code The error code to be checked.

Exception:

The corresponding mdbx::exception.

Friends Documentation

friend operator!=

Compares two error codes for inequality.

friend bool mdbx::error::operator!= (
    const error & a,
    const error & b
)

Parameters:

a The left-hand error.
b The right-hand error.

Returns:

true if the error codes are not equal, false otherwise.

friend operator==

Compares two error codes for equality.

friend bool mdbx::error::operator== (
    const error & a,
    const error & b
)

Parameters:

a The left-hand error.
b The right-hand error.

Returns:

true if the error codes are equal, false otherwise.
