Enum KeyPurpose 

#[non_exhaustive]
pub enum KeyPurpose {
    EncryptDecrypt,
    SignVerify,
    Mac,
}

Intended use of the key.

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.

EncryptDecrypt

Key used for encryption/decryption

SignVerify

Key used for signing/verification

Mac

Key used for message authentication codes

Trait Implementations

impl Clone for KeyPurpose

fn clone(&self) -> KeyPurpose

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for KeyPurpose

impl Debug for KeyPurpose

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeyPurpose

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for KeyPurpose

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

Formats the value using the given formatter.

impl Eq for KeyPurpose

impl PartialEq for KeyPurpose

fn eq(&self, other: &KeyPurpose) -> 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 KeyPurpose

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
