Struct ProxyObjectStorePolicy

Source
pub struct ProxyObjectStorePolicy { /* private fields */ }
Expand description

A policy container, meant to be shared between test code and the proxy object store.

This container allows you to configure policies that should apply to the proxied calls.

Typically, you would use this to simulate I/O errors or mock out data.

Currently, for simplicity, we only proxy calls that involve some kind of path. Calls to copy functions, which have a src and dst, will provide the source to the policy

Implementations§

Source§

impl ProxyObjectStorePolicy

Source

pub fn new() -> Self

Source

pub fn set_before_policy(&mut self, name: &str, policy: Arc<dyn PolicyFnT>)
