Struct rusoto_credential::EnvironmentProvider
source · [−]pub struct EnvironmentProvider { /* private fields */ }
Expand description
Provides AWS credentials from environment variables.
Available Environment Variables
-
AWS_ACCESS_KEY_ID
: -
AWS_SECRET_ACCESS_KEY

AWS_SESSION_TOKEN
: -
AWS_CREDENTIAL_EXPIRATION
:Expiration time in RFC 3339 format (e.g.
1996-12-19T16:39:57-08:00
). If unset, credentials won’t expire.
