Struct PageRead 

pub struct PageRead<C> {
    pub after: Option<C>,
    pub limit: u32,
    pub through: Option<u64>,
}

A page request: an exclusive cursor, a limit and an optional bound.

use doubleentry::PageRead;

let first: PageRead<u64> = PageRead::first(100);
let next = first.clone().after(42).through(1_000);
assert_eq!((next.after, next.limit, next.through), (Some(42), 100, Some(1_000)));

Fields

after: Option<C>

Start after this cursor (None: from the beginning).

limit: u32

The most items to return, 1..=1000.

through: Option<u64>

Read only records below this position (None: the size the read sees). A bound above that size is clamped.

Implementations

impl<C> PageRead<C>

pub const MAX_LIMIT: u32 = 1000

The largest page.

pub const fn first(limit: u32) -> Self

The first page of at most limit items.

pub fn after(self, cursor: C) -> Self

The page after cursor.

pub fn through(self, through: u64) -> Self

The same request, bounded to the records below through.
