Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RETRO_SAVESTATE_CONTEXT_NORMAL = 0

Standard savestate written to disk.

RETRO_SAVESTATE_CONTEXT_RUNAHEAD_SAME_INSTANCE = 1

Savestate where you are guaranteed that the same instance will load the save state. You can store internal pointers to code or data. It’s still a full serialization and deserialization, and could be loaded or saved at any time. It won’t be written to disk or sent over the network.

RETRO_SAVESTATE_CONTEXT_RUNAHEAD_SAME_BINARY = 2

Savestate where you are guaranteed that the same emulator binary will load that savestate. You can skip anything that would slow down saving or loading state but you can not store internal pointers. It won’t be written to disk or sent over the network. Example: “Second Instance” runahead

RETRO_SAVESTATE_CONTEXT_ROLLBACK_NETPLAY = 3

Savestate used within a rollback netplay feature. You should skip anything that would unnecessarily increase bandwidth usage. It won’t be written to disk but it will be sent over the network.

RETRO_SAVESTATE_CONTEXT_UNKNOWN = 2_147_483_647

Ensure sizeof() == sizeof(int).

Trait Implementations

impl Clone for retro_savestate_context

fn clone(&self) -> retro_savestate_context

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for retro_savestate_context

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for retro_savestate_context

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for retro_savestate_context

fn eq(&self, other: &retro_savestate_context) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
