Very small library to create files. It's an alternative to macOS's mkfile(8) that works on everything that has rust's std. I have no idea how fast or perfomant this is, so good luck.

Arguments

• how_many — How many megabytes to write. It can be either in megabytes or gigabytes

• buffer_size — Size of chuck in megabytes. Default value is 16. Meaning empty vector with a size of 16 megabytes will be create in memory

• write_mode — It can either implicitly flush after each chuck or just once at the end.

• file — A Writer to write to. Doesn't have to be a file.

Example

use cavity::{fill, Bytes, WriteMode};
use std::fs::File;
let mut f = File::create("wat.test").unwrap();
fill(Bytes::MegaBytes(5), None, WriteMode::FlushEvery, &mut f).unwrap();
