Messages sent from the worker child to the parent process.

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.

ToolCallRequest

Request the parent to dispatch a tool call.

Fields

request_id: u64

Unique ID for correlating request ↔ response.

server: String

Target server name.

tool: String

Tool identifier.

args: Value

Tool arguments.

ResourceReadRequest

Request the parent to read a resource.

Fields

request_id: u64

Unique ID for correlating request ↔ response.

server: String

Target server name.

uri: String

Resource URI.

StashPut

Request the parent to put a value in the stash.

Fields

request_id: u64

Unique ID for correlating request ↔ response.

key: String

Stash key.

value: Value

Value to store.

ttl_secs: Option<u32>

TTL in seconds (None = use default).

group: Option<String>

Stash group for isolation (v0.3.1+). Absent in v0.3.0 workers → None.

StashGet

Request the parent to get a value from the stash.

Fields

request_id: u64

Unique ID for correlating request ↔ response.

key: String

Stash key.

group: Option<String>

Stash group for isolation (v0.3.1+). Absent in v0.3.0 workers → None.

StashDelete

Request the parent to delete a value from the stash.

Fields

request_id: u64

Unique ID for correlating request ↔ response.

key: String

Stash key.

group: Option<String>

Stash group for isolation (v0.3.1+). Absent in v0.3.0 workers → None.

StashKeys

Request the parent to list stash keys.

Fields

request_id: u64

Unique ID for correlating request ↔ response.

group: Option<String>

Stash group for isolation (v0.3.1+). Absent in v0.3.0 workers → None.

ResetComplete

Worker has been reset and is ready for a new execution.

ExecutionComplete

The execution has finished.

Fields

result: Result<Value, String>

The result value, or an error message.

error_kind: Option<ErrorKind>

Classification of the error for typed reconstruction on the parent side. Present only when result is Err. Defaults to JsError if absent (backward compatibility with workers that don’t send this field).

timeout_ms: Option<u64>

Structured timeout value in milliseconds (v0.3.1+). Present only when error_kind is Timeout. Replaces fragile string parsing. Absent in v0.3.0 workers → None.

Log

A log message from the worker.

Fields

message: String

The log message text.
