Enum Error

pub enum Error<E> {
    Other(E),
    WouldBlock,
}

A non-blocking error

The main use of this enum is to add a WouldBlock variant to an existing error enum.

Variants

Other(E)

A different kind of error

WouldBlock

This operation requires blocking behavior to complete

Implementations

impl<E> Error<E>

pub fn map<T, F>(self, op: F) -> Error<T>

where F: FnOnce(E) -> T,

Maps an Error<E> to Error<T> by applying a function to a contained Error::Other value, leaving an Error::WouldBlock value untouched.

Trait Implementations

impl<E: Clone> Clone for Error<E>

fn clone(&self) -> Error<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E> Debug for Error<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> From<E> for Error<E>

fn from(error: E) -> Error<E>

Converts to this type from the input type.

impl<E: Hash> Hash for Error<E>

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<E: Ord> Ord for Error<E>

fn cmp(&self, other: &Error<E>) -> 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<E: PartialEq> PartialEq for Error<E>

fn eq(&self, other: &Error<E>) -> 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<E: PartialOrd> PartialOrd for Error<E>

fn partial_cmp(&self, other: &Error<E>) -> 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.
