Struct SubjectPublicKeyInfo

pub struct SubjectPublicKeyInfo<'a> {
    pub algorithm: AlgorithmIdentifier<'a>,
    pub subject_public_key: BitString<'a>,
    pub raw: &'a [u8],
}

Fields

algorithm: AlgorithmIdentifier<'a>

subject_public_key: BitString<'a>

raw: &'a [u8]

A raw unparsed PKIX, ASN.1 DER form (see RFC 5280, Section 4.1).

Note: use the Self::parsed() function to parse this object.

Implementations

impl SubjectPublicKeyInfo<'_>

pub fn parsed(&self) -> Result<PublicKey<'_>, X509Error>

Attempt to parse the public key, and return the parsed version or an error

Trait Implementations

impl<'a> Clone for SubjectPublicKeyInfo<'a>

fn clone(&self) -> SubjectPublicKeyInfo<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SubjectPublicKeyInfo<'a>

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

Formats the value using the given formatter.

impl<'a> FromDer<'a, X509Error> for SubjectPublicKeyInfo<'a>

fn from_der(i: &'a [u8]) -> X509Result<'a, Self>

Parse the SubjectPublicKeyInfo struct portion of a DER-encoded X.509 Certificate

impl<'a> PartialEq for SubjectPublicKeyInfo<'a>

fn eq(&self, other: &SubjectPublicKeyInfo<'a>) -> 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.
