Struct SecretVec 

pub struct SecretVec { /* private fields */ }

A heap-allocated, variable-length secret that is automatically zeroed when dropped.

Use SecretVec when the key length is not known at compile time (e.g. RSA private keys, derived key material of arbitrary length).

Implementations

impl SecretVec

pub fn new(bytes: Vec<u8>) -> Self

Create a SecretVec from a Vec<u8>.

pub fn from_slice(slice: &[u8]) -> Self

Create a SecretVec by copying from a slice.

pub fn as_bytes(&self) -> &[u8]

Borrow the secret bytes.

pub fn len(&self) -> usize

Return the length in bytes.

pub fn is_empty(&self) -> bool

Return true if the secret is empty.

Trait Implementations

impl Clone for SecretVec

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SecretVec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SecretVec

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Zeroize for SecretVec

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
