Required Methods

`fn get_tag_list(&self) -> Option<GstRc<TagListRef>>`

Returns the current list of tags the setter uses. The list should not be modified or freed.

This function is not thread-safe.

Returns

a current snapshot of the taglist used in the setter or None if none is used.

`fn get_tag_merge_mode(&self) -> TagMergeMode`

Queries the mode by which tags inside the setter are overwritten by tags from events

Returns

the merge mode used inside the element.

`fn merge_tags(&self, list: &GstRc<TagListRef>, mode: TagMergeMode)`

Merges the given list into the setter's list using the given mode.

`mode`

the mode to merge with

`fn reset_tags(&self)`

Reset the internal taglist. Elements should call this from within the state-change handler.

`fn set_tag_merge_mode(&self, mode: TagMergeMode)`

Sets the given merge mode that is used for adding tags from events to tags specified by this interface. The default is TagMergeMode::Keep, which keeps the tags set with this interface and discards tags from events.

`mode`

The mode with which tags are added
