GSignalQuery: @signal_id: The signal id of the signal being queried, or 0 if the signal to be queried was unknown. @signal_name: The signal name. @itype: The interface/instance type that this signal can be emitted for. @signal_flags: The signal flags as passed in to g_signal_new(). @return_type: The return type for user callbacks. @n_params: The number of parameters that user callbacks take. @param_types: (array length=n_params): The individual parameter types for user callbacks, note that the effective callback signature is: |[ @return_type callback (#gpointer data1, [param_types param_names,] gpointer data2); ]|

A structure holding in-depth information for a specific signal.

Trait Implementations

impl Clone for _GSignalQuery

fn clone(&self) -> _GSignalQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for _GSignalQuery

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

Formats the value using the given formatter.

impl PartialEq for _GSignalQuery

fn eq(&self, other: &_GSignalQuery) -> 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.
