Struct HmacCtxRef 

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

A borrowed reference to a HmacCtx.

Implementations

impl HmacCtxRef

pub fn init(&mut self, key: &[u8], md: &MessageDigest) -> Result<(), ErrorStack>

Configures HmacCtx to use md as the hash function and key as the key.

This corresponds to HMAC_Init_ex.

Trait Implementations

impl AsMut<HmacCtxRef> for HmacCtx

fn as_mut(&mut self) -> &mut HmacCtxRef

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

impl AsRef<HmacCtxRef> for HmacCtx

fn as_ref(&self) -> &HmacCtxRef

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

impl Borrow<HmacCtxRef> for HmacCtx

fn borrow(&self) -> &HmacCtxRef

Immutably borrows from an owned value.

impl BorrowMut<HmacCtxRef> for HmacCtx

fn borrow_mut(&mut self) -> &mut HmacCtxRef
