Struct win_crypto_ng::buffer::Buffer

pub struct Buffer { /* private fields */ }

Secure buffer implementation.

On creation, the buffer is initialized with zeroes. On destruction, if the zeroize feature is enabled, its content is set to 0 before being released.

Implementations

impl Buffer

pub fn new(size: usize) -> Self

Create a new buffer of the specified size.

Examples

let buf = Buffer::new(76);
assert_eq!(buf.len(), 76);

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

Create a new buffer with its data copied from the slice.

Examples

const SOME_DATA: &'static [u8] = &[0x01, 0x02, 0x03, 0x04];
let buf = Buffer::from(SOME_DATA);
assert_eq!(buf.as_slice(), SOME_DATA);

pub fn from_vec(data: Vec<u8>) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn as_ptr(&self) -> *const u8

pub fn as_mut_ptr(&mut self) -> *mut u8

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

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

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

Trait Implementations

impl Debug for Buffer

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

Formats the value using the given formatter.

impl Drop for Buffer

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq<Buffer> for Buffer

fn eq(&self, other: &Buffer) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Buffer> for Buffer

fn partial_cmp(&self, other: &Buffer) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
