Struct rust_libretro::contexts::InitContext

pub struct InitContext<'a> {
    pub(crate) environment_callback: &'a retro_environment_t,
}

Functions that are safe to be called in Core::on_init

Fields

environment_callback: &'a retro_environment_t

Implementations

impl<'a> InitContext<'a>

pub fn new(environment_callback: &'a retro_environment_t) -> Self

impl InitContext<'_>

pub fn get_rumble_interface(&self) -> Option<retro_rumble_interface>

Gets an interface which is used by a libretro core to set state of rumble motors in controllers. A strong and weak motor is supported, and they can be controlled indepedently. Should be called from either Core::on_init or Core::on_load_game. Should not be called from Core::on_set_environment. Returns false if rumble functionality is unavailable.

impl InitContext<'_>

pub unsafe fn set_memory_maps(&self, data: retro_memory_map) -> bool

Unstable This environment call lets a libretro core tell the frontend about the memory maps this core emulates. This can be used to implement, for example, cheats in a core-agnostic way.

Should only be used by emulators; it doesn’t make much sense for anything else. It is recommended to expose all relevant pointers through retro_get_memory_* as well.

Can be called from Core::on_init and Core::on_load_game.

This feature is unstable and guarded by the unstable-env-commands feature flag.

Please be advised that this feature might change without further notice and no guarantees about its stability can be made.

impl InitContext<'_>

pub unsafe fn set_support_achievements(&self, value: bool) -> bool

Unstable If true, the Core implementation supports achievements.

Either via memory descriptors set with RETRO_ENVIRONMENT_SET_MEMORY_MAPS or via Core::get_memory_data / Core::get_memory_size.

This feature is unstable and guarded by the unstable-env-commands feature flag.

Please be advised that this feature might change without further notice and no guarantees about its stability can be made.

impl InitContext<'_>

pub fn set_serialization_quirks(&self, quirks: SerializationQuirks) -> bool

Sets quirk flags associated with serialization. The frontend will zero any flags it doesn’t recognize or support.

Should be set in either Core::on_init or Core::on_load_game, but not both.
