Type Alias io_lifetimes::BorrowedFilelike

pub type BorrowedFilelike<'filelike> = BorrowedFd<'filelike>;

A reference to a filelike object.

This is a portability abstraction over Unix-like BorrowedFd and Windows’ BorrowedHandle.

Aliased Type

struct BorrowedFilelike<'filelike> { /* private fields */ }

Implementations

impl BorrowedFd<'_>

pub const unsafe fn borrow_raw(fd: i32) -> BorrowedFd<'_>

Return a BorrowedFd holding the given raw file descriptor.

Safety

The resource pointed to by fd must remain open for the duration of the returned BorrowedFd, and it must not have the value -1.

impl BorrowedFd<'_>

pub fn try_clone_to_owned(&self) -> Result<OwnedFd, Error>

Creates a new OwnedFd instance that shares the same underlying file description as the existing BorrowedFd instance.

Trait Implementations

impl AsFd for BorrowedFd<'_>

fn as_fd(&self) -> BorrowedFd<'_>

Borrows the file descriptor.

impl AsRawFd for BorrowedFd<'_>

fn as_raw_fd(&self) -> i32

Extracts the raw file descriptor.

impl<'fd> Clone for BorrowedFd<'fd>

fn clone(&self) -> BorrowedFd<'fd>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BorrowedFd<'_>

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

Formats the value using the given formatter.

impl IsTerminal for BorrowedFd<'_>

fn is_terminal(&self) -> bool

Returns true if the descriptor/handle refers to a terminal/tty.
