Struct ToolCompletionHandler 

pub struct ToolCompletionHandler { /* private fields */ }

Tool argument completion handler

This handler provides completion for tool arguments based on the tool’s input schema and available values.

Example

use prism_mcp_rs::core::completion::ToolCompletionHandler;
use std::collections::HashMap;

let mut completions = HashMap::new();
completions.insert("file_reader".to_string(), vec![
("path".to_string(), vec!["/home/user/file1.txt".to_string(), "/home/user/file2.txt".to_string()]),
]);
let handler = ToolCompletionHandler::new(completions);

Implementations

impl ToolCompletionHandler

pub fn new( tool_completions: HashMap<String, Vec<(String, Vec<String>)>>, ) -> Self
