Holds the core instance as well as runtime information from the libretro frontend.

This struct gets used in the code generated by the retro_core!()-macro.

Fields

environment_set: bool

environment_callback: retro_environment_t

video_refresh_callback: retro_video_refresh_t

Render a frame. Pixel format is 15-bit 0RGB1555 native endian unless changed (see RETRO_ENVIRONMENT_SET_PIXEL_FORMAT).

Width and height specify dimensions of buffer. Pitch specifices length in bytes between two lines in buffer.

For performance reasons, it is highly recommended to have a frame that is packed in memory, i.e. pitch == width * byte_per_pixel. Certain graphic APIs, such as OpenGL ES, do not like textures that are not packed in memory.

audio_sample_callback: retro_audio_sample_t

Renders a single audio frame. Should only be used if implementation generates a single sample at a time. Format is signed 16-bit native endian.

audio_sample_batch_callback: retro_audio_sample_batch_t

Renders multiple audio frames in one go.

One frame is defined as a sample of left and right channels, interleaved. I.e. int16_t buf[4] = { l, r, l, r }; would be 2 frames. Only one of the audio callbacks must ever be used.

input_poll_callback: retro_input_poll_t

Polls input.

input_state_callback: retro_input_state_t

Queries for input for player port. device will be masked with RETRO_DEVICE_MASK.

Specialization of devices such as RETRO_DEVICE_JOYPAD_MULTITAP that have been set with Core::on_set_controller_port_device will still use the higher level RETRO_DEVICE_JOYPAD to request input.

rumble_interface: Option<retro_rumble_interface>

sensor_interface: Option<retro_sensor_interface>

camera_interface: Option<retro_camera_callback>

perf_interface: Option<retro_perf_callback>

location_interface: Option<retro_location_callback>

can_dupe: bool

had_frame: bool

last_width: u32

last_height: u32

last_pitch: u64

supports_bitmasks: bool

frame_delta: Option<i64>

core: Box<dyn Core>

The wrapped Core implementation.
