[FEATURE]: Add GLM-4.7 tool calling and reasoning parser support to Rust frontend #5512
Description
Summary
Add support for GLM-4.7 model's tool calling and reasoning parsing in the Rust frontend component.
Background
GLM-4.7 (zai-org/GLM-4.7) requires specific parsers for tool calling and reasoning that are not currently implemented in Dynamo's Rust frontend. vLLM and SGLang support this model with --tool-call-parser glm47 and --reasoning-parser glm45.
Tool Call Parser (glm47)
Format (from tokenizer_config.json):
<tool_call>function_name
<arg_key>param1</arg_key>
<arg_value>value1</arg_value>
<arg_key>param2</arg_key>
<arg_value>value2</arg_value>
</tool_call>
Special tokens:
<tool_call>/</tool_call>- Tool call boundaries<arg_key>/</arg_key>- Argument key wrapper<arg_value>/</arg_value>- Argument value wrapper<tool_response>/</tool_response>- Tool response wrapper (input side)
Reasoning Parser (glm45)
Format (from chat_template.jinja):
<|assistant|><think>reasoning content</think>actual response
Uses standard <think>...</think> tags for reasoning blocks.
