Enum KeyUsage

#[non_exhaustive]
pub enum KeyUsage {
    Master,
    SelfSigning,
    UserSigning,
}

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 values 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.

Implementations

impl KeyUsage

pub fn as_str(&self) -> &str

Available on crate feature events only.

Creates a string slice from this KeyUsage.

Trait Implementations

impl AsRef<str> for KeyUsage

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for KeyUsage

fn clone(&self) -> KeyUsage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KeyUsage

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeyUsage

fn deserialize<D>( deserializer: D, ) -> Result<KeyUsage, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for KeyUsage

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> From<T> for KeyUsage

where T: AsRef<str> + Into<Box<str>>,

fn from(s: T) -> KeyUsage

Converts to this type from the input type.

impl PartialEq for KeyUsage

fn eq(&self, other: &KeyUsage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for KeyUsage

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for KeyUsage

impl StructuralPartialEq for KeyUsage
