Struct aws_smithy_http::property_bag::SharedPropertyBag

pub struct SharedPropertyBag(_);

A wrapper of PropertyBag that can be safely shared across threads and cheaply cloned.

To access properties, use either acquire or acquire_mut. This can be one line for single property accesses, for example:

let my_string = properties.acquire().get::<String>();

For multiple accesses, the acquire result should be stored as a local since calling acquire repeatedly will be slower than calling it once:

let props = properties.acquire();
let my_string = props.get::<String>();
let my_vec = props.get::<Vec<String>>();

Use acquire_mut to insert properties into the bag:

properties.acquire_mut().insert("example".to_string());
