A query for resources.

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

Associated Types

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.
