Struct x11rb::utils::CSlice

pub struct CSlice { /* fields omitted */ }

Wrapper around a slice that was allocated in C code.

CSlice is only available when the allow-unsafe-code feature is enabled.

Implementations

impl CSlice

pub unsafe fn new(ptr: *const u8, len: usize) -> CSlice

Constructs a new CSlice from the given parts. libc::free will be called on the given pointer when the slice is dropped.

Safety

The same rules as for std::slice::from_raw_parts apply. Additionally, the given pointer must be safe to free with libc::free.

pub fn into_ptr(self) -> *const u8

Convert self into a raw part.

Ownership of the returned pointer is given to the caller. Specifically, libc::free will not be called on it by CSlice.

Trait Implementations

impl AsRef<[u8]> for CSlice

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

Performs the conversion.

impl Debug for CSlice

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

Formats the value using the given formatter.

impl Deref for CSlice

type Target = [u8]

The resulting type after dereferencing.

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

Dereferences the value.

impl Drop for CSlice

fn drop(&mut self)

Executes the destructor for this type.

impl<I> Index<I> for CSlice where
    I: SliceIndex<[u8]>, 

type Output = I::Output

The returned type after indexing.

fn index(&self, index: I) -> &I::Output

Performs the indexing (container[index]) operation.
