Enum nb::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: Copy> Copy for Error<E>

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: Eq> Eq for Error<E>

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

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

Performs the conversion.

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, 

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.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl<E: PartialEq> PartialEq<Error<E>> for Error<E>

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

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

fn ne(&self, other: &Error<E>) -> bool

This method tests for !=.

impl<E: PartialOrd> PartialOrd<Error<E>> 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: &Error<E>) -> bool

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

fn le(&self, other: &Error<E>) -> bool

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

fn gt(&self, other: &Error<E>) -> bool

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

fn ge(&self, other: &Error<E>) -> bool

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