Added feature `mapped-file`: Attempt to `mmap()` input where possible to avoid reads. (NOTE: This should be replaced with a cfg-target-unix check, for now it is a default feature that can be disabled.) 		2 months ago

reverse

Collects input, reverses it, then outputs it.

Usage

From arguments:

$ reverse 1 2 3 4
4
3
2
1

From standard input:

$ find . | reverse

Standard input is read line by line, unlike arguments. The two cannot be combined.

Build

Requires rust and cargo installed:

$ cargo build --release

The outputted binary will be ./target/release/reverse.

Customise behaviour

There are several compile-time flags. See ./Cargo.toml for the description of each one.

To build with custom features:

$ cargo build --release --no-default-features --features <your feature>,...

This is a toy project I used to play around with what I could do with slice patterns in Rust.
