Struct aws_smithy_client::erase::DynConnector
source · [−]#[non_exhaustive]pub struct DynConnector(_);
Expand description
A Smithy connector that uses dynamic dispatch.
This type allows you to pay a small runtime cost to avoid having to name the exact connector
you’re using anywhere you want to hold a Client
. Specifically, this will use Box
to
enable dynamic dispatch for every request that goes through the connector, which increases
memory pressure and suffers an additional vtable indirection for each request, but is unlikely
to matter in all but the highest-performance settings.
