Struct openstack::object_storage::ObjectQuery

pub struct ObjectQuery { /* fields omitted */ }

A query to objects.

Implementations

impl ObjectQuery

pub fn with_marker<T: Into<String>>(self, marker: T) -> Self

Add marker to the request.

Using this disables automatic pagination.

pub fn with_limit(self, limit: usize) -> Self

Add limit to the request.

Using this disables automatic pagination.

pub fn into_iter(self) -> ResourceIterator<ObjectQuery>

Convert this query into an iterator executing the request.

Returns a FallibleIterator, which is an iterator with each next call returning a Result.

Note that no requests are done until you start iterating.

pub fn all(self) -> Result<Vec<Object>>

Execute this request and return all results.

A convenience shortcut for self.into_iter().collect().

pub fn one(self) -> Result<Object>

Return one and exactly one result.

Fails with ResourceNotFound if the query produces no results and with TooManyItems if the query produces more than one result.

Trait Implementations

impl Clone for ObjectQuery

fn clone(&self) -> ObjectQuery

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
