Struct Page

pub struct Page { /* private fields */ }
Expand description

Page struct for pagination.

This is a simple struct to handle pagination for queries.


#[derive(Table, Debug, Default, Clone, serde::Serialize, serde::Deserialize)]
pub struct Users {
    pub id: PrimaryKeyInteger,
    pub username: String,
    pub age: i32,
    pub postcode: Option<String>,
}

// Create a new Page instance
let mut page = Page::new();

// Update the page to the next page
page.next();


// Build a query to select rows from the table
let select_query = Users::query_select()
    .where_eq("username", "geekmasher")
    .page(&page)
    .order_by("age", QueryOrder::Asc)
    .build()
    .expect("Failed to build select query");

let page_max = Page::from((1, 10_000));

let option_page = Page::from((Some(5), Some(10)));
