Struct aws_smithy_http::property_bag::SharedPropertyBag
source · [−]pub struct SharedPropertyBag(_);
Expand description
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());
