Struct libcryptsetup_rs::SafeBorrowedMemZero

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

Handle for zeroing borrowed memory. “Borrowed” in this context refers to memory that will be cleaned up by some other scope and is not required to be freed by the caller. An example of this would be a char * pointer to kernel memory where the caller can access the memory but is not responsible for its allocation or deallocation.

Implementations

impl SafeBorrowedMemZero

pub unsafe fn from_ptr(ptr: *mut c_void, size: usize) -> Self

Construct a safe memory handle from a pointer and a size.

Safety

The length must match the length of the exposed memory block or memory corruption could occur.

Trait Implementations

impl AsMut<[u8]> for SafeBorrowedMemZero

fn as_mut(&mut self) -> &mut [u8]

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

impl AsRef<[u8]> for SafeBorrowedMemZero

fn as_ref(&self) -> &[u8]

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

impl Drop for SafeBorrowedMemZero

fn drop(&mut self)

Executes the destructor for this type.

impl SafeMemzero for SafeBorrowedMemZero

fn safe_memzero(&mut self)

Zero the data in the buffer. To enable managed zeroing of a buffer, call this in a Drop implementation.
