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.
