Struct webpki::KeyUsage

pub struct KeyUsage { /* private fields */ }

The expected key usage of a certificate.

This type represents the expected key usage of an end entity certificate. Although for most kinds of certificates the extended key usage extension is optional (and so certificates not carrying a particular value in the EKU extension are acceptable). If the extension is present, the certificate MUST only be used for one of the purposes indicated.
