a clone of C sprintf 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 this crate unless you specificaly need printf compatibility.
This crate implements a dynamically type-checked function vsprintf and macro
sprintf!.
Usage example:
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 dependency as it is used in the tests to compare results. std
is used for some maths functions.
