PageQuery

Struct PageQuery 

Source
pub struct PageQuery {
    pub page: u64,
    pub page_size: u64,
}
Expand description

分页查询参数(公共类型,所有 crate 可用)

Fields§

§page: u64

页码(从 1 开始)

§page_size: u64

每页条数

Implementations§

Source§

impl PageQuery

Source

pub fn new(page: u64, page_size: u64) -> PageQuery

创建分页参数,自动规整到合法范围

  • page: 页码,最小为 1
  • page_size: 每页条数,范围 [1, 1000]

超出范围的值会被自动修正到边界。

Source

pub fn offset(&self) -> u64

计算 SQL OFFSET:(page - 1) * page_size

Source

pub fn limit(&self) -> u64

获取 LIMIT 值(即 page_size
