Struct graphql_starter::pagination::Page

pub struct Page<T> {
    pub page_info: PageInfo,
    pub total_items: Option<u64>,
    pub edges: Vec<Edge<T>>,
}

One page of the cursor-based pagination

Fields

page_info: PageInfo

The current page information

total_items: Option<u64>

Total number of items queried, before pagination

edges: Vec<Edge<T>>

The edges on this page

Implementations

impl<T> Page<T>

pub fn new( has_previous_page: bool, has_next_page: bool, total_items: Option<u64>, edges: Vec<Edge<T>> ) -> Self

Builds a new Page

pub fn from_iter<I: IntoIterator<Item = Edge<T>>>( has_previous_page: bool, has_next_page: bool, total_items: Option<u64>, edges: I ) -> Self

Builds a new Page

pub fn with_total_items(self, total_items: u64) -> Self

Sets the total_items to Some

pub fn map<Z, F>(self, map: F) -> Page<Z>

where F: FnMut(Edge<T>) -> Edge<Z>,

Takes a closure to map each element

pub fn try_map<Z, F, E>(self, map: F) -> Result<Page<Z>, E>

where F: FnMut(Edge<T>) -> Result<Edge<Z>, E>,

Takes a closure to try to map each element

pub fn map_node<Z, F>(self, map: F) -> Page<Z>

where F: Fn(T) -> Z,

Takes a closure to map each element node

pub fn try_map_node<Z, F, E>(self, map: F) -> Result<Page<Z>, E>

where F: Fn(T) -> Result<Z, E>,

Takes a closure to try to map each element node

pub fn from_items(items: Vec<T>, page: PageQuery) -> Result<Self>

Builds a new Page from all of the items, useful when mocking or storage doesn’t support paging
