Module tool_call 

Qwen tool-call output parsing.

The model emits each call as XML-style markup: an outer tool marker, a function element carrying the name, and one parameter element per argument. Argument text is untyped; a terminal contract built from the request’s tool schemas normalizes it into JSON values. A type mismatch stays a structured call for consumer validation; only a structure or identity failure returns the whole marker region to ordinary content.

Structs

ParsedToolCallOutput 🔒

RawParameter 🔒

RawToolCall 🔒

RegionParser 🔒

Terminal 🔒

Tool 🔒

ToolCallOutputContract 🔒

Parameter names and declared types gathered from the request’s tool schemas. Guidance only: schemas never validate the whole call.

ToolCallOutputDecoder 🔒

Incrementally publishes bytes that are provably outside a possible terminal Qwen tool-call suffix. Bytes that could belong to a marker are held back; at terminal time, valid calls are retained structurally and malformed output is restored verbatim.

ToolCallParseDiagnostics 🔒

WireToolCall 🔒

Server-minted wire shape for one decoded model tool call.

Upper bound on model-emitted function names. Request-side names use a shorter grammar on the wire.

Functions

admits_value 🔒

classify_json_value 🔒

compile_direct_types 🔒

Record the supported top-level types from a type keyword.

compile_schema_types 🔒

Compile the type set from a property schema’s type, anyOf, or oneOf.

encode_json_string 🔒

fallback 🔒

is_ws 🔒

json_number_is_integer 🔒

1e5 is 100000; integer classification must respect the exponent.

normalize_declared_parameter 🔒

normalize_parameter 🔒

normalize_raw_tool_call 🔒

parse_qwen_tool_call_output 🔒

Parse the Qwen XML-like tool-call format. Content before the first marker is retained as ordinary text; a malformed marker region falls back to the whole input, marker included. Tolerant mode recovers complete calls from a truncated or suffixed region.

same_tool 🔒

schema_bit 🔒

skip_ws 🔒

starts_at 🔒

strip_parameter_framing 🔒

Parameter values are framed by newlines; a string-typed parameter keeps them, other types trim.
