Struct clircle::UnixIdentifier

pub struct UnixIdentifier { /* private fields */ }

Implementation of Clircle for Unix.

Implementations

impl UnixIdentifier

pub unsafe fn try_from_raw_fd(fd: RawFd, owns_fd: bool) -> Result<Self>

Creates a UnixIdentifier from a raw file descriptor. The preferred way to create a UnixIdentifier is through one of the TryFrom implementations.

Safety

The owns_fd argument should only be true, if the given file descriptor owns the resource it points to (for example a file). If it is true, a File can be obtained back with Clircle::into_inner, or it will be closed when the UnixIdentifier is dropped.

Errors

The underlying call to File::metadata fails.

Trait Implementations

impl Clircle for UnixIdentifier

fn surely_conflicts_with(&self, other: &Self) -> bool

This method implements the conflict check that is used in the GNU coreutils program cat.

fn into_inner(self) -> Option<File>

Returns the File that was used for From<File>. If the instance was created otherwise, this may also return None.

fn stdin() -> Option<Self>

Shorthand for try_from(Stdio::Stdin).

fn stdout() -> Option<Self>

Shorthand for try_from(Stdio::Stdout).

fn stderr() -> Option<Self>

Shorthand for try_from(Stdio::Stderr).

impl Debug for UnixIdentifier

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

Formats the value using the given formatter.

impl Drop for UnixIdentifier

fn drop(&mut self)

Executes the destructor for this type.

impl Hash for UnixIdentifier

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<UnixIdentifier> for UnixIdentifier

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<File> for UnixIdentifier

type Error = Error

The type returned in the event of a conversion error.

fn try_from(file: File) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Stdio> for UnixIdentifier

type Error = <UnixIdentifier as TryFrom<File>>::Error

The type returned in the event of a conversion error.

fn try_from(stdio: Stdio) -> Result<Self, Self::Error>

Performs the conversion.
