Module runtime 

Structs

ToolCallChunk

Streamed tool output emitted before the final tool response frame.

ToolCallRequest

A tool call request as seen by the kernel.

ToolCallResponse

The kernel’s response to a tool call request.

ToolCallStream

Complete streamed output captured by the kernel.

ToolInvocationCost

Cost reported by a tool server after invocation.

Enums

ToolCallOutput

Output produced by a tool invocation.

ToolServerEvent

ToolServerOutput

Tool-server output produced after validation and guard checks.

ToolServerStreamResult

Stream-capable tool-server result.

Verdict

Verdict of a guard or capability evaluation.

Traits

NestedFlowBridge

Bridge exposed to tool-server implementations while a parent request is in flight.

NestedFlowClient

Raw client transport used by the kernel to service nested flows on behalf of a parent request.

ToolServerConnection

Trait representing a connection to a tool server.

Functions

enforce_stream_byte_limit

Sum the canonical byte size of a materialized stream and deny with Overloaded { StreamBytes } if it exceeds max_total_bytes (0 = unlimited). Uses the same per-chunk measurement as truncate_stream_to_limits, so the at-arrival count and the finalize-time count agree by construction.

push_chunk_bounded

Fallible per-chunk push for KernelError-returning accumulators. Denies before materializing past max_total_bytes (StreamBytes) OR past max_chunks retained chunks (StreamChunks), and maps a failed allocation under strict overcommit to a typed deny (Allocation) rather than an abort.
