Struct PageInfo 

pub struct PageInfo {
    pub page: u64,
    pub page_size: u32,
    pub total_items: u64,
    pub total_pages: u64,
    pub has_next: bool,
    pub has_prev: bool,
}

Page information for offset-based pagination

Fields

page: u64

Current page number (0-based)

page_size: u32

Number of items per page

total_items: u64

Total number of items

total_pages: u64

Total number of pages

has_next: bool

Whether there is a next page

has_prev: bool

Whether there is a previous page

Implementations

impl PageInfo

pub fn from_total(total: u64, request: &PaginationRequest) -> Self

Create page information from total count and pagination request

Examples

let request = PaginationRequest::offset(40, 20);
let info = PageInfo::from_total(100, &request);
assert_eq!(info.page, 2);
assert_eq!(info.total_pages, 5);
assert!(info.has_next);
assert!(info.has_prev);

Trait Implementations

impl Clone for PageInfo

fn clone(&self) -> PageInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PageInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PageInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PageInfo

fn eq(&self, other: &PageInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PageInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
