Type Alias spki::AlgorithmIdentifierRef

pub type AlgorithmIdentifierRef<'a> = AlgorithmIdentifier<AnyRef<'a>>;

AlgorithmIdentifier reference which has AnyRef parameters.

Aliased Type

struct AlgorithmIdentifierRef<'a> {
    pub oid: ObjectIdentifier,
    pub parameters: Option<AnyRef<'a>>,
}

Fields

oid: ObjectIdentifier

Algorithm OID, i.e. the algorithm field in the AlgorithmIdentifier ASN.1 schema.

parameters: Option<AnyRef<'a>>

Algorithm parameters.

Implementations

impl<'a> AlgorithmIdentifierRef<'a>

pub fn assert_parameters_oid( &self, expected_oid: ObjectIdentifier, ) -> Result<ObjectIdentifier>

Assert parameters is an OID and has the expected value.

pub fn assert_oids( &self, algorithm: ObjectIdentifier, parameters: ObjectIdentifier, ) -> Result<()>

Assert the values of the algorithm and parameters OIDs.

pub fn parameters_any(&self) -> Result<AnyRef<'a>>

Get the parameters field as an AnyRef.

Returns an error if parameters are None.

pub fn parameters_oid(&self) -> Result<ObjectIdentifier>

Get the parameters field as an ObjectIdentifier.

Returns an error if it is absent or not an OID.

pub fn oids(&self) -> Result<(ObjectIdentifier, Option<ObjectIdentifier>)>

Convert to a pair of ObjectIdentifiers.

This method is helpful for decomposing in match statements. Note in particular that NULL parameters are treated the same as missing parameters.

Returns an error if parameters are present but not an OID.

Trait Implementations

impl<'a> RefToOwned<'a> for AlgorithmIdentifierRef<'a>

type Owned = AlgorithmIdentifier<Any>

The resulting type after obtaining ownership.

fn ref_to_owned(&self) -> Self::Owned

Creates a new object taking ownership of the data
