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:

toml [dependencies] swrite = "0.0.1"

In your Rust code:

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

Examples

Using swrite! and swriteln! with a String:

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

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

println!("{}", s); ```

Output:

not_rust Hello, world! The answer is 42.
