Struct openssl::bn::BigNumContext

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

Temporary storage for BigNums on the secure heap

BigNum values are stored dynamically and therefore can be expensive to allocate. BigNumContext and the OpenSSL BN_CTX structure are used internally when passing BigNum values between subroutines.

Implementations

impl BigNumContext

pub fn new() -> Result<BigNumContext, ErrorStack>

Returns a new BigNumContext.

This corresponds to BN_CTX_new.

pub fn new_secure() -> Result<BigNumContext, ErrorStack>

Returns a new secure BigNumContext.

This corresponds to BN_CTX_secure_new.

Trait Implementations

impl AsRef<BigNumContextRef> for BigNumContext

fn as_ref(&self) -> &BigNumContextRef

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

impl Borrow<BigNumContextRef> for BigNumContext

fn borrow(&self) -> &BigNumContextRef

Immutably borrows from an owned value.

impl Deref for BigNumContext

type Target = BigNumContextRef

The resulting type after dereferencing.

fn deref(&self) -> &BigNumContextRef

Dereferences the value.

impl DerefMut for BigNumContext

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

Mutably dereferences the value.

impl Drop for BigNumContext

fn drop(&mut self)

Executes the destructor for this type.

impl ForeignType for BigNumContext

type CType = BN_CTX

The raw C type.

type Ref = BigNumContextRef

The type representing a reference to this type.

unsafe fn from_ptr(ptr: *mut BN_CTX) -> BigNumContext

Constructs an instance of this type from its raw type.

fn as_ptr(&self) -> *mut BN_CTX

Returns a raw pointer to the wrapped value.
