ifmt

A small crate which brings inline string interpolation to rust's standard formatting macros.

Getting started

To use ifmt in your project, add

[dependencies]
ifmt = "0.1.1"

to your Cargo.toml.

Usage

Nightly

Since procedural macros currently cannot be used in expression position on stable, this crate requires you to use nightly rust and enable #![feature(proc_macro_hygiene)].

Examples

let four = 4;
iprintln!("four plus four is: {four + 4}");
// four plus four is: 8
iprintln!("here's a hex number: 0x{0xb0bi64 * 1321517i64 :x}");
// here's a hex number: 0xdeadbeef
iprintln!("here's a debugging value: {Some(four):?}");
// here's a debugging value: Some(4)

Supported macros

format!      -> iformat!
print!       -> iprint!
println!     -> iprintln!
eprint!      -> ieprint!
eprintln!    -> ieprintln!
write!       -> iwrite!
