Adding `swrite` library as a dependency

Run this command in a terminal, in your project's directory:

Readme

swrite

swrite is a tiny Rust crate providing the swrite! and swriteln! macros as infallible alternatives to write! and writeln! for Strings. This is safe because writing to a String never returns Err(_).

The implementation uses the SWrite trait. It is implemented for String. With the osstring feature is enabled, it is also implemented for std::ffi::OsString.

Minimum Supported Rust Version (MSRV):

Without the osstring feature (default): 1.30.0
With the osstring feature: 1.64.0

Usage

In Cargo.toml:

[dependencies]
swrite = "0.1.0"

In your Rust code:

use swrite::{SWrite, swrite, swriteln};

Examples

Using swrite! and swriteln! with a String:

use swrite::{SWrite, swrite, swriteln};

let mut s = String::new();
swrite!(s, "Hello, {}! ", "world");
swriteln!(s, "The answer is {}.", 42);

println!("{}", s);

Output:

Hello, world! The answer is 42.
