[−] Expand description

A query for resources.

This is a low-level trait that should not be used directly.

Associated Types

type Item[−]

Item type.

Associated Constants

const DEFAULT_LIMIT: usize[−]

Default limit to use with this query.

Required methods

fn can_paginate(&self) -> Result<bool>[−]

Whether pagination is supported for this query.

fn extract_marker(&self, resource: &Self::Item) -> String[−]

Extract a marker from a resource.

fn fetch_chunk(
    &self,
    limit: Option<usize>,
    marker: Option<String>
) -> Result<Vec<Self::Item>>[−]

Get a chunk of resources.

Provided methods

fn validate(&mut self) -> Result<()>[−]

Validate the query before the first execution.

This call may modify internal representation of the query, so changing the query after calling it may cause undesired side effects.
