Enum ruma_common::encryption::KeyUsage

#[non_exhaustive]
pub enum KeyUsage {
    Master,
    SelfSigning,
    UserSigning,
    // some variants omitted
}

The usage of a cross signing key.

This type can hold an arbitrary string. To build this with a custom value, convert it from a string with ::from() / .into(). To check for formats that are not available as a documented variant here, use its string representation, obtained through .as_str().

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Master

Master key.

SelfSigning

Self-signing key.

UserSigning

User-signing key.
