Struct aws_smithy_http_server::extension::Extension

source · [−]

pub struct Extension<T>(pub T);

Expand description

Generic extension type stored in and extracted from request extensions.

This is commonly used to share state across handlers.

If the extension is missing it will reject the request with a 500 Internal Server Error response.
