Struct FunctionTool 

pub struct FunctionTool { /* private fields */ }

A single-struct tool that carries metadata, JSON schema, and an async handler

Implementations

impl FunctionTool

pub fn builder( name: impl Into<String>, description: impl Into<String>, ) -> FunctionToolBuilder

pub fn from_schema<F, Fut>( name: impl Into<String>, description: impl Into<String>, schema: Value, f: F, ) -> ToolResult<FunctionTool>

where F: Fn(Value) -> Fut + Send + Sync + 'static, Fut: Future<Output = ToolResult<Value>> + Send + 'static,

Convenience: build a FunctionTool directly from a full JSON schema and a handler

pub fn from_function_spec<F, Fut>(spec: Value, f: F) -> ToolResult<FunctionTool>

where F: Fn(Value) -> Fut + Send + Sync + 'static, Fut: Future<Output = ToolResult<Value>> + Send + 'static,

Build a FunctionTool from a full JSON spec (supports two shapes):

1. {“name”:…, “description”:…, “parameters”: {…}}
2. {“type”:“function”, “function”: {“name”:…, “description”:…, “parameters”: {…}}}

pub fn from_function_spec_file<F, Fut>( path: impl AsRef<Path>, f: F, ) -> ToolResult<FunctionTool>

where F: Fn(Value) -> Fut + Send + Sync + 'static, Fut: Future<Output = ToolResult<Value>> + Send + 'static,

Read a JSON function spec from a file and build a FunctionTool.
