Struct x509_parser::x509::AlgorithmIdentifier

pub struct AlgorithmIdentifier<'a> {
    pub algorithm: Oid<'a>,
    pub parameters: Option<Any<'a>>,
}

Algorithm identifier

An algorithm identifier is defined by the following ASN.1 structure:

AlgorithmIdentifier  ::=  SEQUENCE  {
     algorithm               OBJECT IDENTIFIER,
     parameters              ANY DEFINED BY algorithm OPTIONAL  }

The algorithm identifier is used to identify a cryptographic algorithm. The OBJECT IDENTIFIER component identifies the algorithm (such as DSA with SHA-1). The contents of the optional parameters field will vary according to the algorithm identified.

Fields

algorithm: Oid<'a>

parameters: Option<Any<'a>>

Implementations

impl<'a> AlgorithmIdentifier<'a>

pub const fn new(algorithm: Oid<'a>, parameters: Option<Any<'a>>) -> Self

Create a new AlgorithmIdentifier

pub const fn oid(&'a self) -> &'a Oid<'_>

Get the algorithm OID

pub const fn parameters(&'a self) -> Option<&'a Any<'_>>

Get a reference to the algorithm parameters, if present

Trait Implementations

impl<'ber, 'a> CheckDerConstraints for AlgorithmIdentifier<'a>

where 'ber: 'a,

fn check_constraints(any: &Any<'_>) -> Result<()>

impl<'a> Clone for AlgorithmIdentifier<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for AlgorithmIdentifier<'a>

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

Formats the value using the given formatter.

impl<'ber, 'a> FromDer<'ber, X509Error> for AlgorithmIdentifier<'a>

where 'ber: 'a,

fn from_der(bytes: &'ber [u8]) -> ParseResult<'ber, Self, X509Error>

Attempt to parse input bytes into a DER object (enforcing constraints)

impl<'a> PartialEq for AlgorithmIdentifier<'a>

fn eq(&self, other: &AlgorithmIdentifier<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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