Struct libmpv_sys::mpv_render_param

#[repr(C)]pub struct mpv_render_param {
    pub type_: mpv_render_param_type,
    pub data: *mut c_void,
}

Used to pass arbitrary parameters to some mpv_render_* functions. The meaning of the data parameter is determined by the type, and each MPV_RENDER_PARAM_* documents what type the value must point to.

Each value documents the required data type as the pointer you cast to void* and set on mpv_render_param.data. For example, if MPV_RENDER_PARAM_FOO documents the type as Something* , then the code should look like this:

Something foo = {...}; mpv_render_param param; param.type = MPV_RENDER_PARAM_FOO; param.data = & foo;

Normally, the data field points to exactly 1 object. If the type is char*, it points to a 0-terminated string.

In all cases (unless documented otherwise) the pointers need to remain valid during the call only. Unless otherwise documented, the API functions will not write to the params array or any data pointed to it.

As a convention, parameter arrays are always terminated by type==0. There is no specific order of the parameters required. The order of the 2 fields in this struct is guaranteed (even after ABI changes).
