Struct 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.

impl Send for BigNumContext

impl Sync for BigNumContext

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
