=====
A grab-bag of useful functions for functional programming.
* Docs: https://docs.rs/tool/
* Build Status: [](https://travis-ci.org/Stebalien/tool-rs)
* Crate: [tool](https://crates.io/crates/tool)
## Example
### Non-empty strings
```rust
extern crate tool;
use tool::prelude::*;
fn main() {
let strings: Vec<_> = vec!["my string", "", "asdf", ""]
.into_iter()
.filter(non_empty)
.collect();
assert_eq!(strings, vec!["my string", "asdf"]);
}
```
### First item in an iterator of tuples.
```rust
extern crate tool;
use tool::prelude::*;
fn main() {
let strings: Vec<_> = vec![("first", 1), ("second", 2), ("third", 3), ("fourth", 4)]
.into_iter()
.map(first)
.collect();
assert_eq!(strings, vec!["first", "second", "third", "fourth"]);
}
```
## Compile-Time Flags (cargo features)
* `use_std` (default: enabled) - Disable this if you're project doesn't depend on libstd.
