This library provides a interface to create database pages.

A page is a fixed size buffer that can be used to store data.

Example

In your cargo.toml: [dependencies] flex-page = "1"

```rust use std::fs::File; use flex_page::Pages;

let file = File::options() .read(true) .write(true) .create(true) .open("test1.db")?;

// 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 = Pages::open(file)?;

// Create a page. pages.create([0; 4096]).await?;

// Overwrite a page. pages.write(1, [1; 4096]).await?;

// Reading a page and write to it. // It also lock the page num. So, this page can't be read by other thread. let mut page = pages.goto(1).await?; assert_eq!(page.buf, [1; 4096]);

// Write to the page. // It drops the lock. So, this page can be accessable by other thread. page.write_buf([2; 4096]).await?;

// Read a page. asserteq!(pages.read(1).await?.asref(), &[2; 4096]); ```
