Trait Implementations

impl AsRawFd for ManagedFD

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Clone for ManagedFD

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ManagedFD

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

Formats the value using the given formatter.

impl Drop for ManagedFD

fn drop(&mut self)

Executes the destructor for this type.

impl From<ManagedFD> for File

fn from(from: ManagedFD) -> Self

Converts to this type from the input type.

impl From<MemoryFile> for ManagedFD

fn from(from: MemoryFile) -> Self

Converts to this type from the input type.

impl From<UnmanagedFD> for ManagedFD

fn from(from: UnmanagedFD) -> Self

Converts to this type from the input type.

impl FromRawFd for ManagedFD

unsafe fn from_raw_fd(fd: RawFd) -> Self

Constructs a new instance of Self from the given raw file descriptor.

impl Hash for ManagedFD

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,

Feeds a slice of this type into the given Hasher.

impl IntoRawFd for ManagedFD

fn into_raw_fd(self) -> RawFd

Consumes this object, returning the raw underlying file descriptor.

impl Ord for ManagedFD

fn cmp(&self, other: &ManagedFD) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ManagedFD> for ManagedFD

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

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

const 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 PartialOrd<ManagedFD> for ManagedFD

fn partial_cmp(&self, other: &ManagedFD) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
