You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: command.rs
    path of file: ./repos/edma/tui/src/components/database
    
    the code of the file until where you have to start completion: use crate::{
	components::{render_container, RenderAbleComponent},
	config::Config,
	constants::{BORDER_TYPE, HIGHLIGHT_COLOR},
	events::{EventState, Key},
};
use anyhow::Result;
use tui::{
	backend::Backend,
	layout::Rect,
	style::{Color, Modifier, Style},
	text::Text,
	widgets::{Block, Borders, Paragraph},
	Frame,
};
use tui_t
    
	fn handle_command(&mut self) {
		let mapped: Vec<_> = self.text.iter().map(|t| t.to_string()).collect();
		let complete = mapped.join("");
		let splitted = complete.split(' ');
		for token in splitted {
			match token {
				t if token.starts_with("COLUMN") | token.starts_with("TABLE") => {
					let value = t.split('=').nth(1);
					match value {
						Some(v) => self.add_command(Command {
							token: "COLUMN".to_string(),
							value: v.to_string(),
						}),
						None => {
							return self.set_invalid(true, "No COLUMN value found");
						}
					}
				}
				t if token.starts_with("TREE") => {
					let value = t.split('=').nth(1);
					match value {
						Some(v) => self.add_command(Command {
							token: "TREE".to_string(),
							value: v.to_string(),
						}),
						None => {
							return self.set_invalid(true, "No TREE value found");
						}
					}
				}
				t if token.starts_with("PREFIX") => {
					let value = t.split('=').nth(1);
					match value {
						Some(v) => self.add_command(Command {
							token: "PREFIX".to_string(),
							value: v.replace('"', "").to_string(),
						}),
						None => {
							return self.set_invalid(true, "No PREFIX value found");
						}
					}
				}
				t if token.starts_with("SUFFIX") => {
					let value = t.split('=').nth(1);
					match value {
						Some(v) => self.add_command(Command {
							token: "SUFFIX".to_string(),
							value: v.replace('"', "").to_string(),
						}),
						None => {
							return self.set_invalid(true, "No SUFFIX value found");
						}
					}
				}
				_ => return self.set_invalid(true, "Mismatch command"),

		self.set_invalid(false, "");
