Struct DefaultEngine 

pub struct DefaultEngine { /* private fields */ }

Standalone engine: crypto via KeyRing, sprites via CpuRenderer. infer returns EngineError::Unsupported — real inference needs the engine feature (combs-runtime), wired up in combs-mesh-ffi.

Implementations

impl DefaultEngine

pub fn new() -> Self

Creates an uninitialized engine (call init before crypto ops).

Trait Implementations

impl CombsEngineCore for DefaultEngine

fn init(&self, key: &[u8]) -> Result<(), EngineError>

Initializes the engine with a master key (HKDF input).

fn infer(&self, _prompt: &str) -> Result<String, EngineError>

Runs inference on prompt. Requires the engine feature.

fn encrypt_memory(&self, data: &[u8]) -> Result<Vec<u8>, EngineError>

Encrypts a memory blob (nonce-prefixed AEAD).

fn decrypt_memory(&self, data: &[u8]) -> Result<Vec<u8>, EngineError>

Decrypts a blob produced by CombsEngineCore::encrypt_memory.

fn render_sprite( &self, emoji: &Emoji, frame_index: u32, ) -> Result<Vec<u8>, EngineError>

Renders frame frame_index of the emoji’s first sprite atlas to RGBA8 bytes.

fn shutdown(&self) -> Result<(), EngineError>

Shuts the engine down, zeroizing key material.

impl Default for DefaultEngine

fn default() -> Self

Returns the “default value” for a type.
