Struct openssl::asn1::Asn1Integer

source ·
pub struct Asn1Integer(/* private fields */);
Expand description

Numeric representation

Integers in ASN.1 may include BigNum, int64 or uint64. BigNum implementation can be found within bn module.

OpenSSL documentation includes ASN1_INTEGER_set.

Implementations§

source§

impl Asn1Integer

source

pub fn from_bn(bn: &BigNumRef) -> Result<Self, ErrorStack>

Converts a bignum to an Asn1Integer.

Corresponds to BN_to_ASN1_INTEGER. Also see BigNumRef::to_asn1_integer.

Methods from Deref<Target = Asn1IntegerRef>§

source

pub fn get(&self) -> i64

👎Deprecated since 0.10.6: use to_bn instead
source

pub fn to_bn(&self) -> Result<BigNum, ErrorStack>

Converts the integer to a BigNum.

This corresponds to ASN1_INTEGER_to_BN.

source

pub fn set(&mut self, value: i32) -> Result<(), ErrorStack>

Sets the ASN.1 value to the value of a signed 32-bit integer, for larger numbers see bn.

This corresponds to ASN1_INTEGER_set.

source

pub fn to_owned(&self) -> Result<Asn1Integer, ErrorStack>

Creates a new Asn1Integer with the same value.

This corresponds to ASN1_INTEGER_dup.
