Implementations§

source§

impl Pagination

source

pub const fn try_new( before: Option<Ulid>, after: Option<Ulid>, first: Option<usize>, last: Option<usize>, ) -> Result<Self, InvalidPagination>

Creates a new Pagination from user-provided parameters.

§Errors

Either first or last must be provided, else this function will return an InvalidPagination error.

pub const fn last(last: usize) -> Self

Creates a Pagination which gets the last N items

source

pub const fn before(self, id: Ulid) -> Self

Get items before the given cursor

source

pub const fn clear_before(self) -> Self

Clear the before cursor

source

pub const fn after(self, id: Ulid) -> Self

Get items after the given cursor

source

pub const fn clear_after(self) -> Self
