Struct KeyUsage 

pub struct KeyUsage(pub u32);

Bitmask of key usage bits from an X.509 keyUsage extension.

Returned by X509::key_usage. Combine constants with | or test individual bits with Self::contains.

Tuple Fields

0: u32

Implementations

impl KeyUsage

pub const DIGITAL_SIGNATURE: Self

digitalSignature — signing data and authentication.

pub const NON_REPUDIATION: Self

nonRepudiation (contentCommitment in RFC 5280).

pub const KEY_ENCIPHERMENT: Self

keyEncipherment — encrypting symmetric keys.

pub const DATA_ENCIPHERMENT: Self

dataEncipherment — directly encrypting data.

pub const KEY_AGREEMENT: Self

keyAgreement — Diffie-Hellman key exchange.

pub const KEY_CERT_SIGN: Self

keyCertSign — signing certificates.

pub const CRL_SIGN: Self

cRLSign — signing CRLs.

pub const ENCIPHER_ONLY: Self

encipherOnly — only encrypt during key agreement.

pub const DECIPHER_ONLY: Self

decipherOnly — only decrypt during key agreement.

pub fn contains(self, flag: Self) -> bool

Return true if all bits in flag are set in self.

pub fn bits(self) -> u32

Return the raw bitmask value.

Trait Implementations

impl BitAnd for KeyUsage

type Output = KeyUsage

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self

Performs the & operation.

impl BitOr for KeyUsage

type Output = KeyUsage

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl Clone for KeyUsage

fn clone(&self) -> KeyUsage

Returns a duplicate 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

Formats the value using the given formatter.

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.
