Struct KernelInstance 

pub struct KernelInstance { /* private fields */ }

一个节点持有的算子实例。Drop 时回调 C 侧 destroy(RAII)。

Implementations

impl KernelInstance

pub fn create(kernel_name: &str) -> Result<Self>

pub fn create_route(config: RouteConfig) -> Self

pub fn kernel_name(&self) -> &str

pub fn language(&self) -> KernelLanguage

pub unsafe fn fill_contract( kernel_name: &str, contract: *mut c_void, ) -> Result<()>

调 C 侧 get_contract 填充契约。

Safety

contract 必须是指向存活 Contract 的有效指针,且在本调用期间不被其它代码访问。

pub unsafe fn open(&self, ctx: *mut c_void) -> i32

以下三者传入的 ctx 是 *mut Context 的擦除形式。 调用期间不持有任何引擎锁(docs/design.md §7.0 R1)。

Safety

ctx 必须是指向存活 crate::context::Context 的有效指针,且调用方持有 本节点的独占令牌(docs/design.md §7.0 R3)—— 否则算子回调可能与引擎 对同一 Context 的访问竞争。

pub unsafe fn process(&self, ctx: *mut c_void) -> i32

Safety

同 Self::open。

pub unsafe fn close(&self, ctx: *mut c_void) -> i32

Safety

同 Self::open。

Trait Implementations

impl Debug for KernelInstance

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

Formats the value using the given formatter.

impl Drop for KernelInstance

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
