ascii-literal

A proc-macro to make compile-time checked AsciiStrs.

Examples

This compiles just fine, and works as you would expect.

use ascii_literal::ascii_literal;
const MESSAGE: &ascii::AsciiStr = ascii_literal!("Hello in ASCII!");
println!("{}", MESSAGE); // Prints "Hello in ASCII!"

This, however, will give a compile time error.

use ascii_literal::ascii_literal;
// This doesn't compile!
const NOT_ASCII: &ascii::AsciiStr = ascii_literal!("Boom! 💥");
