is_ok
public bool is_ok()
Defined at line 279 of file ../../sdk/lib/fit/include/lib/fit/result.h

error_value
public E & error_value()

take_error
public error<E> take_error()
Defined at line 314 of file ../../sdk/lib/fit/include/lib/fit/result.h
Moves the underlying error and returns it as an instance of fit::error, simplifying propagating the error to another fit::result.
May only be called when the result contains an error.

value_or
public T value_or(U && default_value)
Defined at line 364 of file ../../sdk/lib/fit/include/lib/fit/result.h
Contingent accessors for the underlying value.
Returns the value when the result has a value, otherwise returns the given default value.

operator->
public decltype(auto) operator->()
Defined at line 382 of file ../../sdk/lib/fit/include/lib/fit/result.h

May only be called when the result contains a value.

operator*
public T & operator*()
Defined at line 398 of file ../../sdk/lib/fit/include/lib/fit/result.h

Defined at line 410 of file ../../sdk/lib/fit/include/lib/fit/result.h
Augments the error value of the result with the given error value. The operator E::operator+=(F) must be defined. Additionally, E may not be a pointer, primitive, or enum type.
May only be called when the result contains an error.
map_error
public result<std::invoke_result_t<Fn, E>, T> map_error(Fn && fn)
Defined at line 428 of file ../../sdk/lib/fit/include/lib/fit/result.h
Maps a result<E, T> to a result<E2, T> by transforming the error through fn, where E2 is the result of invoking fn on E. Success values will be passed through untouched.
Note that map_error is not necessary if E2 is constructible from E. In that case, result<E2, T> will be constructible from result<E, T>.
If the current object is an r-value, errors and successes in the current result object will be moved.

Default constructs a result in empty state.
reset
protected void reset()
Defined at line 469 of file ../../sdk/lib/fit/include/lib/fit/result.h
Reset is not a recommended operation for the general result pattern. This method is provided for derived types that need it for specific use cases.
