Write a self-contained Rust program that prints a JSON output of how often each word appears in a text file located in /tmp/file.txt. So if the file contains "This is is is, an example" then the program should print to stdout. {"This": 1, "is": 2, "is,": 1, "an": 1, "example": 1} Don't import any crates that would require a Cargo.toml file. I'll just compile it with `rustc yourfile.rs` and it should work. The program should be run by calling /path/to/rust_word_count with no arguments

# Rust Word Count Program Here's a self-contained Rust program that counts word frequency and outputs JSON:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | use std::fs::File; use std::io::{self, Read}; use std::collections::HashMap; fn main() -> io::Result<()> { // Read the file content let mut file = File::open("/tmp/file.txt")?; let mut content = String::new(); file.read_to_string(&mut content)?; // Count word frequencies let mut word_counts = HashMap::new(); for word in content.split_whitespace() { *word_counts.entry(word.to_string()).or_insert(0) += 1; } // Create JSON output let mut json_output = String::from("{"); let mut first = true; for (word, count) in word_counts.iter() { if !first { json_output.push_str(", "); } first = false; json_output.push_str(&format!("\"{}\": {}", word, count)); } json_output.push_str("}"); println!("{}", json_output); Ok(()) } |

I extracted the following code from that output:
