Struct CSemiBox

pub struct CSemiBox<'a, D>
where
    D: DisposeRef + 'a + ?Sized,
{ /* private fields */ }

A wrapper for pointers made by C that are now partially owned in Rust.

This is necessary to allow owned and borrowed representations of C types to be represented by the same type as they are in C with little overhead

Implementations

impl<'a, D> CSemiBox<'a, D>

where D: DisposeRef + 'a + ?Sized,

pub fn new(ptr: *mut D::RefTo) -> Self

Wrap the pointer in a CSemiBox

pub unsafe fn as_ptr(&self) -> *mut D::RefTo

Returns the internal pointer

pub unsafe fn unwrap(self) -> *mut D::RefTo

Returns the internal pointer

Trait Implementations

impl<'a, D> Borrow<D> for CSemiBox<'a, D>

where D: DisposeRef + 'a, *mut D::RefTo: Into<&'a D>,

fn borrow(&self) -> &D

Immutably borrows from an owned value.

impl<'a, T> Debug for CSemiBox<'a, T>

where T: Debug + DisposeRef + 'a, *mut T::RefTo: Into<&'a T>,

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

Formats the value using the given formatter.

impl<'a, D> Deref for CSemiBox<'a, D>

where D: DisposeRef + 'a, *mut D::RefTo: Into<&'a D>,

type Target = D

The resulting type after dereferencing.

fn deref(&self) -> &D

Dereferences the value.

impl<'a, D> DerefMut for CSemiBox<'a, D>

where D: DisposeRef + 'a, *mut D::RefTo: Into<&'a D> + Into<&'a mut D>,

fn deref_mut(&mut self) -> &mut D

Mutably dereferences the value.

impl<'a, T> Display for CSemiBox<'a, T>

where T: Display + DisposeRef + 'a, *mut T::RefTo: Into<&'a T>,

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

Formats the value using the given formatter.

impl<'a, D> Drop for CSemiBox<'a, D>

where D: DisposeRef + 'a + ?Sized,

fn drop(&mut self)

Run the destructor

impl<'a> From<&'a CStr> for CSemiBox<'a, str>

fn from(text: &'a CStr) -> CSemiBox<'a, str>

Converts to this type from the input type.

impl<'a, D> From<*mut <D as DisposeRef>::RefTo> for CSemiBox<'a, D>

where D: DisposeRef + 'a + ?Sized,

fn from(ptr: *mut D::RefTo) -> Self

Converts to this type from the input type.

impl<'a, T> PartialEq<T> for CSemiBox<'a, T>

where T: 'a + DisposeRef + PartialEq, *mut T::RefTo: Into<&'a T>,

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

Tests for self and other values to be equal, and is used by ==.

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

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