a clone of C s(n)printf in Rust
This crate was created out of a desire to provide C printf-style formatting in a WASM program, where there is no libc.
Note: You're probably better off using standard Rust string formatting instead of thie crate unless you specificaly need printf compatibility.
This crate implements a dynamically type-checked function vsprintf and macro
sprintf!.
Usage example:
rust
use sprintf::sprintf;
let s = sprintf!("%d + %d = %d\n", 3, 9, 3+9).unwrap();
assert_eq!(s, "3 + 9 = 12\n");
libc is a dev devependency as it is used in the tests to compare results.
