Struct KeyUsage 

pub struct KeyUsage { /* private fields */ }

The X.509 keyUsage extension (RFC 5280 §4.2.1.3) as a bitfield.

A public BIT STRING read — NOT a trust decision. Which bits a role requires is decided by verify_chain / tlcp::chain::verify_pair, not by parsing. Bit 0 is the most-significant bit of the first content byte (DER BIT STRING order); bits 0–8 are named below.

Implementations

impl KeyUsage

pub const fn digital_signature(self) -> bool

digitalSignature (bit 0).

pub const fn content_commitment(self) -> bool

nonRepudiation / contentCommitment (bit 1).

pub const fn key_encipherment(self) -> bool

keyEncipherment (bit 2).

pub const fn data_encipherment(self) -> bool

dataEncipherment (bit 3).

pub const fn key_agreement(self) -> bool

keyAgreement (bit 4).

pub const fn key_cert_sign(self) -> bool

keyCertSign (bit 5).

pub const fn crl_sign(self) -> bool

cRLSign (bit 6).

pub const fn encipher_only(self) -> bool

encipherOnly (bit 7).

pub const fn decipher_only(self) -> bool

decipherOnly (bit 8).

Trait Implementations

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 Copy for KeyUsage

impl Debug for KeyUsage

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

Formats the value using the given formatter.

impl Eq for KeyUsage

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.
