This library provides a interface to create database pages.
A page is a fixed size buffer that can be used to store data.
In your cargo.toml:
toml
[dependencies]
flex-page = "2"
```rust use std::fs::{File, removefile}; use flexpage::Pages;
let file = File::options() .read(true) .write(true) .create(true) .open("foo").unwrap();
// First generic argument is the page number type. Number of page that can be stored in the file. // Second generic argument is the size of the page. let pages: Pages<64> = Pages::open(file).unwrap();
// Create a page. pages.create([1; 64]).unwrap();
// Overwrite a page. pages.write(0, [2; 64]).unwrap();
// Read a page. assert_eq!(pages.read(0).unwrap(), [2; 64]);
assert_eq!(pages.len(), 1);
// Alloc 2 more pages pages.alloc(2).unwrap();
assert_eq!(pages.len(), 3);
removefile("foo_"); ```
