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 Do not import serde_json, write json output from scratch.

The program should be run by calling /path/to/rust_word_count with no arguments Do not import serde_json, write json output from scratch.
Here's a self-contained Rust program that reads a text file located at `/tmp/file.txt`, counts the occurrences of each word, and prints the results in JSON format. You can compile it using `rustc` without needing any external crates.

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 Do not import serde_json, write json output from scratch.

Certainly! Below is a self-contained Rust program that reads a text file located at `/tmp/file.txt`, counts the occurrences of each word, and prints the result in JSON format. The program does not use any external crates, so it can be compiled directly with `rustc`.
