impl Eq for Fd

impl<'a> Extend<&'a Fd> for FdSet

fn extend<I: IntoIterator<Item = &'a Fd>>(&mut self, iter: I)

Extends a collection with the contents of an iterator.

impl Extend<Fd> for FdSet

fn extend<I: IntoIterator<Item = Fd>>(&mut self, iter: I)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

impl From<Fd> for FdSet

fn from(fd: Fd) -> Self

Converts to this type from the input type.

impl From<i32> for Fd

fn from(raw_fd: RawFd) -> Fd

Converts to this type from the input type.

impl FromIterator<Fd> for FdSet

fn from_iter<I: IntoIterator<Item = Fd>>(iter: I) -> Self

Creates a value from an iterator.

impl Hash for Fd

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 Ord for Fd

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Fd

fn eq(&self, other: &Fd) -> 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.

impl PartialOrd for Fd

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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