Function libmpv_sys::mpv_event_to_node

pub unsafe extern "C" fn mpv_event_to_node(
    dst: *mut mpv_node, 
    src: *mut mpv_event
) -> c_int

Convert the given src event to a mpv_node, and set *dst to the result. dst is set to a MPV_FORMAT_NODE_MAP, with fields for corresponding mpv_event and mpv_event.data/mpv_event_ fields.

The exact details are not completely documented out of laziness. A start is located in the "Events" section of the manpage.

*dst may point to newly allocated memory, or pointers in mpv_event. You must copy the entire mpv_node if you want to reference it after mpv_event becomes invalid (such as making a new mpv_wait_event() call, or destroying the mpv_handle from which it was returned). Call mpv_free_node_contents() to free any memory allocations made by this API function.

Safe to be called from mpv render API threads.

@param dst Target. This is not read and fully overwritten. Must be released with mpv_free_node_contents(). Do not write to pointers returned by it. (On error, this may be left as an empty node.) @param src The source event. Not modified (it's not const due to the author's prejudice of the C version of const). @return error code (MPV_ERROR_NOMEM only, if at all)
