}

Function table the host passes to every controller plug-in instance.

Each service accepts a JSON request envelope and returns a JSON response envelope as OwnedBytes. The producing side owns and frees returned allocations so host and plug-in allocators remain isolated.

Fields

abi_version: u32

ABI version of this vtable. Must equal NAUTILUS_PLUGIN_ABI_VERSION.

create_plugin_strategy: unsafe extern "C" fn(ctx: *const ControllerHostContext, request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>

Creates a plug-in strategy through the host’s registered controller.

start_strategy: unsafe extern "C" fn(ctx: *const ControllerHostContext, request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>

Starts a strategy through the host’s system controller command path.

stop_strategy: unsafe extern "C" fn(ctx: *const ControllerHostContext, request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>

Stops a strategy through the host’s system controller command path.

exit_market: unsafe extern "C" fn(ctx: *const ControllerHostContext, request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>

Exits the market for a strategy through the system controller.

remove_strategy: unsafe extern "C" fn(ctx: *const ControllerHostContext, request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>

Removes a strategy through the system controller.

instrument_exists: unsafe extern "C" fn(ctx: *const ControllerHostContext, request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>

Checks whether an instrument is present in the host cache.

log: unsafe extern "C" fn(ctx: *const ControllerHostContext, request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>

Emits a structured log record through the host logger.

clock_now_ns: unsafe extern "C" fn(ctx: *const ControllerHostContext, request_json: BorrowedStr<'_>) -> PluginResult<OwnedBytes>

Returns the host clock reading in a JSON response envelope.

Implementations

impl ControllerHostVTable

pub fn matches_compiled_abi(&self) -> bool

Asserts that the embedded ABI version matches the compiled-in constant.

Trait Implementations

impl Send for ControllerHostVTable

SAFETY: function pointers are thread-safe by construction; the host guarantees the underlying implementations are Sync.

impl Sync for ControllerHostVTable

SAFETY: see above.
