Type Alias AlgorithmIdentifierRef 

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

AlgorithmIdentifier reference which has AnyRef parameters.

Aliased Type

pub struct AlgorithmIdentifierRef<'a> {
    pub oid: ObjectIdentifier<39>,
    pub parameters: Option<AnyRef<'a>>,
}

Fields

oid: ObjectIdentifier<39>

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.

Errors

Returns Error::OidUnknown if self.parameters_oid() doesn’t match expected_oid.

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

Assert the values of the algorithm and parameters OIDs.

Errors

Returns Error::OidUnknown if algorithm and/or parameters aren’t the expected values.

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

Get the parameters field as an AnyRef.

Errors

Returns Error::AlgorithmParametersMissing error if self.parameters are None.

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

Get the parameters field as an ObjectIdentifier.

Errors

• Returns Error::AlgorithmParametersMissing error if self.parameters are None.
• Returns Error::Asn1 if self.parameters is 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.

Errors

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
