#### Classes

Info | `GWeatherInfo` provides a handy way to access weather conditions and forecasts from a `GWeatherLocation`, aggregating multiple different web services.
Location | A `GWeatherLocation` represents a “location” of some type known to libgweather; anything from a single weather station to the entire world.

#### Structs

Conditions | A convenient way to describe the current or forecast weather phenomenon, if significant, and its associated modifier. If the value is not significant, the weather conditions are described by `gweather_info_get_sky()` instead.

#### Aliases

MoonLatitude | The moon declension, in degrees.
MoonPhase | The current phase of the moon, represented as degrees, where 0 is the new moon, 90 is the first quarter, etc.

#### Enumerations

ConditionPhenomenon | The current or forecasted significant phenomenon.
ConditionQualifier | An additional modifier applied to a `GWeatherConditionPhenomenon` to describe the current or forecasted weather conditions.
DistanceUnit | The measure unit to use for sky visibility values, when retrieved by gweather_info_get_value_visibility().
LocationLevel | The size/scope of a particular `GWeatherLocation`.
PressureUnit | The measure unit to use for atmospheric pressure values, when retrieved by gweather_info_get_value_pressure().
Sky | The sky and cloud visibility. In general it is discouraged to use this value directly to compute the forecast icon: applications should instead use `gweather_info_get_icon_name()` or gweather_info_get_symbolic_icon_name().
SpeedUnit | The measure unit to use for wind speed values, when retrieved by gweather_info_get_value_wind().
TemperatureUnit | The measure unit to use for temperature values, when retrieved by the `gweather_info_get_value_temp()` family of functions.
WindDirection | The direction of the prevailing wind. Composite values such as north-north-east indicate a direction between the two component value (north and north-east).

#### Bitfields

FormatOptions | Format options to influence the text returned by the `gweather_*_to_string_full()` functions.
Provider |

#### Callbacks

FilterFunc | A filter function for locations.
