Crate shorten

Objective:

A collection of convenience functions, macros and traits to shorten repetitive code.

Status

Experimental

Version

0.1.3

Example 1:

Shorten the convertion to a String.

s!("Hello") is the same as String::from("Hello"))

Example 2:

Concatenate two string(s) (slices) and return a string slice.

ss!("Hello", ", world") is the same as "Hello, world";

The same macro works also with an arbitrarz combination of String objects and string slices

// #[macro_use] extern crate shorten;
// use shorten::*;
// let s1 = s!("Hello");
// let s2 = s!(", world");
// assert_eq!(ss!(s1, s2), "Hello, world");

Example 3:

// #[macro_use] extern crate shorten; ```rust use shorten::*; let v = fread(".gitignore").unwrap();

// Convert to a String

// Option 1: Safe. Consumes the vector and complains about invalid UTF-8 let s = String::from_utf8(v).expect("Found invalid UTF-8");

// Option 2: Lossy. It turns invalid UTF-8 bytes into � and so no error handling is required let s = String::from_utf8_lossy(&v[..]).into_owned(); // Does NOT consume v ???

// Option 3: Convert to a u8 array (not Vec) and then to a string slice. // The conversion is in-place, and does not require an allocation. You can create a String from the slice if necessary. let s = std::str::from_utf8(&v[..]).unwrap(); // Does NOT consume v ??? ```

Macros
