Struct Asn1Integer

pub struct Asn1Integer(/* private fields */);

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

impl Asn1Integer

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>

pub fn get(&self) -> i64

👎Deprecated since 0.10.6: use to_bn instead

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

Converts the integer to a BigNum.

This corresponds to ASN1_INTEGER_to_BN.

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.

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

Creates a new Asn1Integer with the same value.

This corresponds to ASN1_INTEGER_dup.

Trait Implementations

impl AsRef<Asn1IntegerRef> for Asn1Integer

fn as_ref(&self) -> &Asn1IntegerRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<Asn1IntegerRef> for Asn1Integer

fn borrow(&self) -> &Asn1IntegerRef

Immutably borrows from an owned value.

impl Deref for Asn1Integer

type Target = Asn1IntegerRef

The resulting type after dereferencing.

fn deref(&self) -> &Asn1IntegerRef

Dereferences the value.

impl DerefMut for Asn1Integer

fn deref_mut(&mut self) -> &mut Asn1IntegerRef

Mutably dereferences the value.

impl Drop for Asn1Integer

fn drop(&mut self)

Executes the destructor for this type.

impl ForeignType for Asn1Integer

type CType = ASN1_INTEGER

The raw C type.

type Ref = Asn1IntegerRef

The type representing a reference to this type.

unsafe fn from_ptr(ptr: *mut ASN1_INTEGER) -> Asn1Integer

Constructs an instance of this type from its raw type.

fn as_ptr(&self) -> *mut ASN1_INTEGER

Returns a raw pointer to the wrapped value.

impl Ord for Asn1Integer

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Asn1Integer

fn eq(&self, other: &Asn1Integer) -> 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.

impl PartialOrd for Asn1Integer

fn partial_cmp(&self, other: &Asn1Integer) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
