Struct RedoubtCodecBuffer 

pub struct RedoubtCodecBuffer { /* private fields */ }

Implementations

impl RedoubtCodecBuffer

pub fn with_capacity(capacity: usize) -> Self

pub fn realloc_with_capacity(&mut self, capacity: usize)

pub fn clear(&mut self)

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

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn write<T>(&mut self, src: &mut T) -> Result<(), RedoubtCodecBufferError>

pub fn write_slice<T>( &mut self, src: &mut [T], ) -> Result<(), RedoubtCodecBufferError>

pub fn export_as_vec(&mut self) -> Vec<u8>

Exports the buffer contents as a Vec<u8> and zeroizes the internal buffer.

This method creates a new Vec containing a copy of the buffer’s data, then immediately zeroizes the internal buffer. The zeroization ensures that sensitive data is cleared from the RedoubtCodecBuffer after export, preventing potential memory leaks of plaintext data.

Security

The zeroization happens after copying the data to the returned Vec, ensuring the internal buffer is always cleaned up when data is exported. This is crucial when the RedoubtCodecBuffer contains sensitive plaintext that should not remain in memory after encoding is complete.

Example

let mut buf = RedoubtCodecBuffer::with_capacity(10);
buf.write_usize(&42).unwrap();
let exported = buf.export_as_vec();
// buf is now zeroized, exported contains the data

Trait Implementations

impl AssertZeroizeOnDrop for RedoubtCodecBuffer

fn clone_sentinel(&self) -> ZeroizeOnDropSentinel

Clones the internal ZeroizeOnDropSentinel for verification.

fn assert_zeroize_on_drop(self)

Asserts that zeroization happens when this value is dropped.

impl Default for RedoubtCodecBuffer

fn default() -> Self

Returns the “default value” for a type.

impl Drop for RedoubtCodecBuffer

Available on crate feature zeroize only.

fn drop(&mut self)

Executes the destructor for this type.

impl FastZeroizable for RedoubtCodecBuffer

fn fast_zeroize(&mut self)

Zeroizes the value in place.

impl ZeroizationProbe for RedoubtCodecBuffer

fn is_zeroized(&self) -> bool
