Struct aws_config::environment::region::EnvironmentVariableRegionProvider

pub struct EnvironmentVariableRegionProvider { /* private fields */ }

Expand description

Load a region from environment variables

This provider will first check the value of AWS_REGION, falling back to AWS_DEFAULT_REGION when AWS_REGION is unset.
