GIconIface: @g_iface: The parent interface. @hash: A hash for a given #GIcon. @equal: Checks if two #GIcons are equal. @to_tokens: Serializes a #GIcon into tokens. The tokens must not contain any whitespace. Don’t implement if the #GIcon can’t be serialized (Since 2.20). @from_tokens: Constructs a #GIcon from tokens. Set the #GError if the tokens are malformed. Don’t implement if the #GIcon can’t be serialized (Since 2.20). @serialize: Serializes a #GIcon into a #GVariant. Since: 2.38

GIconIface is used to implement GIcon types for various different systems. See #GThemedIcon and #GLoadableIcon for examples of how to implement this interface.

Fields

g_iface: GTypeInterface

hash: Option<unsafe extern "C" fn(icon: *mut GIcon) -> guint>

equal: Option<unsafe extern "C" fn(icon1: *mut GIcon, icon2: *mut GIcon) -> gboolean>

to_tokens: Option<unsafe extern "C" fn(icon: *mut GIcon, tokens: *mut GPtrArray, out_version: *mut gint) -> gboolean>

GIconIface::to_tokens: @icon: The #GIcon @tokens: (element-type utf8) (out caller-allocates): The array to fill with tokens @out_version: (out): version of serialized tokens

Serializes the @icon into string tokens. This is can be invoked when g_icon_new_for_string() is called.

Returns: %TRUE if serialization took place, %FALSE otherwise

Since: 2.20

from_tokens: Option<unsafe extern "C" fn(tokens: *mut *mut gchar, num_tokens: gint, version: gint, error: *mut *mut GError) -> *mut GIcon>

GIconIface::from_tokens: @tokens: (array length=num_tokens): An array of tokens @num_tokens: The number of tokens in @tokens @version: Version of the serialized tokens @error: Return location for errors, or %NULL to ignore

Constructs a #GIcon from a list of @tokens.

Returns: (nullable) (transfer full): the #GIcon or %NULL on error

Since: 2.20

serialize: Option<unsafe extern "C" fn(icon: *mut GIcon) -> *mut GVariant>

Trait Implementations

impl Clone for _GIconIface

fn clone(&self) -> _GIconIface

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for _GIconIface

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for _GIconIface

fn eq(&self, other: &_GIconIface) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
