Member Function Documentation

error()

Result contur::Result< void >::error ( ErrorCode code )

inlinestaticnodiscard

Constructs a failed void Result with the given error code.

Definition at line 195 of file error.h.

errorCode()

ErrorCode contur::Result< void >::errorCode ( ) const

inlinenodiscardnoexcept

Returns the error code (Ok if successful).

Definition at line 214 of file error.h.

isError()

bool contur::Result< void >::isError ( ) const

inlinenodiscardnoexcept

Returns true if this Result represents failure.

Definition at line 208 of file error.h.

isOk()

bool contur::Result< void >::isOk ( ) const

inlinenodiscardnoexcept

Returns true if this Result represents success.

Definition at line 202 of file error.h.

ok()

Result contur::Result< void >::ok ( )

inlinestaticnodiscard

Constructs a successful void Result.

Definition at line 189 of file error.h.

value()

const void & contur::Result< void >::value ( ) const &

inlinenodiscard

Returns a const reference to the success value.

Precondition

isOk() must be true. Undefined behavior otherwise.

Definition at line 133 of file error.h.

valueOr()

void contur::Result< void >::valueOr ( void defaultValue ) const &

inlinenodiscard

Returns the value if ok, or the provided default value if error.
