Struct unsafe_io::UnsafeFile

#[repr(transparent)]
pub struct UnsafeFile(_);

A non-owning unsafe I/O handle which on Windows is limited to handling what Windows considers to be RawHandles—mainly files and pipes.

Implementations

impl UnsafeFile

#[must_use]

pub const fn as_unowned_unsafe_handle(self) -> UnsafeHandle

Like AsUnsafeHandle::as_unsafe_handle, but isn’t unsafe because it doesn’t imply a dereference.

#[must_use]

pub const fn into_unowned_unsafe_handle(self) -> UnsafeHandle

Like IntoUnsafeHandle::into_unsafe_handle, but isn’t unsafe because it doesn’t imply a dereference.

#[must_use]

pub const fn as_unowned_raw_handle(self) -> RawHandle

Like AsRawHandle::as_raw_handle, but isn’t unsafe because it doesn’t imply a dereference.

#[must_use]

pub const fn into_unowned_raw_handle(self) -> RawHandle

Like IntoRawHandle::into_raw_handle, but isn’t unsafe because it doesn’t imply a dereference.

pub const fn unowned_from_raw_handle(raw_handle: RawHandle) -> Self

Like FromRawHandle::from_raw_handle, but isn’t unsafe because it doesn’t imply a dereference.

Trait Implementations

impl AsRawHandle for UnsafeFile

UnsafeFile doesn’t own its handle; see the comments for impl AsRawFd for UnsafeHandle.

fn as_raw_handle(&self) -> RawHandle

Extracts the raw handle, without taking any ownership.

impl AsRawHandleOrSocket for UnsafeFile

UnsafeFile doesn’t own its handle; see the comments for impl AsRawFd for UnsafeHandle.

fn as_raw_handle_or_socket(&self) -> RawHandleOrSocket

Like AsRawHandle::as_raw_handle and AsRawSocket::as_raw_socket but can return either type.

impl Clone for UnsafeFile

fn clone(&self) -> UnsafeFile

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnsafeFile

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

Formats the value using the given formatter.

impl FromRawHandle for UnsafeFile

UnsafeFile doesn’t own its handle; see the comments for impl AsRawFd for UnsafeHandle.

unsafe fn from_raw_handle(raw_handle: RawHandle) -> Self

Constructs a new I/O object from the specified raw handle.

impl IntoRawHandle for UnsafeFile

UnsafeFile doesn’t own its handle; see the comments for impl AsRawFd for UnsafeHandle.

fn into_raw_handle(self) -> RawHandle

Consumes this object, returning the raw underlying handle.

impl IntoRawHandleOrSocket for UnsafeFile

UnsafeFile doesn’t own its handle; see the comments for impl AsRawFd for UnsafeHandle.

fn into_raw_handle_or_socket(self) -> RawHandleOrSocket

Like IntoRawHandle::into_raw_handle and IntoRawSocket::into_raw_socket but can return either type.

impl Copy for UnsafeFile

impl Send for UnsafeFile

The Windows HANDLE type may be sent between threads (despite containing a *mut void, which in general isn’t Send).
