Struct SecureBuffer 

pub struct SecureBuffer { /* private fields */ }

A buffer that zeros itself on drop.

Implementations

impl SecureBuffer

pub fn new(capacity: usize) -> Self

Create a new secure buffer with the given capacity.

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

Create a secure buffer from bytes.

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

Create a secure buffer from a slice.

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

Get a reference to the inner bytes.

pub fn as_bytes_mut(&mut self) -> &mut [u8]

Get a mutable reference to the inner bytes.

pub fn len(&self) -> usize

Get the length of the buffer.

pub fn is_empty(&self) -> bool

Check if the buffer is empty.

pub fn push(&mut self, byte: u8)

Push a byte to the buffer.

pub fn extend_from_slice(&mut self, slice: &[u8])

Extend the buffer with a slice.

pub fn clear(&mut self)

Clear the buffer (zeroizes first).

pub fn into_inner(self) -> Vec<u8>

Consume the buffer and return the inner Vec (without zeroing).

Use with caution - the returned Vec will not be zeroized on drop.

pub fn resize(&mut self, new_len: usize)

Resize the buffer to the new length, filling with zeros.

Trait Implementations

impl Clone for SecureBuffer

fn clone(&self) -> SecureBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SecureBuffer

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

Formats the value using the given formatter.

impl From<&[u8]> for SecureBuffer

fn from(data: &[u8]) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for SecureBuffer

fn from(data: Vec<u8>) -> Self

Converts to this type from the input type.

impl Zeroize for SecureBuffer

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.
