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 = "0.4"

```rust use flex_page::Pages;

// 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("test.db")?;

// 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]); page.buf = [2; 4096];

// Write to the page. // It drops the lock. So, this page can be accessable by other thread. page.write().await?;

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