vec-string-to-static-str

vec-string-to-static-str is a Rust library providing utilities for converting vectors of Strings into vectors of &'static str. This library includes both safe and unsafe methods for achieving this conversion.

Features

Safe conversion of String to &'static str with Box::leak
Unsafe conversion of String to &'static str using std::mem::transmute

Usage

Add vec_string_to_static_str to your Cargo.toml:

[dependencies]
vec-string-to-static-str = "1.0.0"

Make sure to add the "unsafe" feature flag to enable unsafe_vec_string_to_static_str if needed.

Example

use vec_string_to_static_str::{vec_string_to_static_str, unsafe_vec_string_to_static_str};

fn main() {
    let strings = vec![String::from("hello"), String::from("world")];

    // Safe method
    let static_strs = vec_string_to_static_str(&strings);
    assert_eq!(static_strs, vec!["hello", "world"]);

    // Unsafe method
    let unsafe_static_strs = unsafe_vec_string_to_static_str(&strings);
    assert_eq!(unsafe_static_strs, vec!["hello", "world"]);
}

Safety

Safe Method: Uses Box::leak to convert String to &'static str, which leaks memory.
Unsafe Method: Uses std::mem::transmute to extend the lifetime of string slices, which can cause undefined behavior if not used correctly.
